BabelColor FAQ

7- (macOS Sierra) Why cant the program find its Help manual, the sample files, the default CMYK profiles, or the display calibration files for the i1Display Pro? This question is applicable to PatchTool Version 5.0 or OLDER (This question does not apply to PatchTool 5.1). This can happen if PatchTool was downloaded AFTER the installation of macOS Sierra AND if the Mac is not configured to accept applications downloaded from “Anywhere”. You will find more info on how to set the proper permissions in the Mac OS Compatibility page.

6- Can I make an ICC printer profile using PatchTool? No, PatchTool cannot generate an ICC profile. However, PatchTool has tools to check printer profiles; please consult Application Note AN-3a on printer proofing for information on the Idealliance printer certification procedure.

5- Can I use PatchTool to profile my monitor? No, PatchTool cannot generate an ICC profile. The Display-Check feature in PatchTool is dedicated, as its name says, to check your monitor calibration. Since PatchTool is color managed, it will use the default ICC display profile, or any other user- assigned profile, to display calibrated colors. Many calibration software offer a small utility, with basic features, to validate the profile they generate. PatchTool's Display-Check is a flexible tool designed to independently validate monitor calibration, where you can define your own color list, of any size, and have a complete overview on how the measured data is processed. Please consult Application Note AN-4a on monitor proofing for information on the Idealliance monitor certification procedure.

4- My i1Pro/i1Pro 2 is detected but I get an error message when I calibrate. What is wrong? Calibration failure more often occurs when calibrating in reflectance mode. This can happen even if the instrument is properly detected and identified in the 'Information info' dialog. Here are potential causes to look for: 1. The instrument is not properly seated on the calibration tile. This may seem obvious but it is worth checking! 2. The calibration tile is dirty. Clean it gently with a soft tissue lightly dabbed in isopropyl alcohol. 3. You are using the wrong calibration tile for the instrument. The i1Pro calibration tile is matched to the instrument at the factory. You should be aware that using a tile from another instrument will very likely provide inaccurate measurements, even if you do not get an error message! 4. There is a bad or degraded contact between the instrument and the USB cable or between the cable and the computer USB port. If a connection is loose, you can sometimes improve it by pushing, holding, or reinserting the connector. Try another USB cable or another USB port to see if you get better results. In some extreme cases your computer USB port or your instrument connector may need to be replaced. 5. The overall USB cable resistance is too high. This can be due to a poor quality cable, a damaged cable, a cable which is too long, or a cable with dirty connectors. 6. The computer USB port cannot provide enough current for calibration. This is more often a problem with external USB hubs. Try a USB port which is not used (i.e. connected and disconnected) often. 7. If all of the above is non-conclusive, your instrument may be due for a factory calibration or repair. The i1Pro requires more power when calibrating in reflectance mode because current must be supplied to its lamp. If the overall cable plus connectors electrical resistance is too high, this will lower the actual voltage applied to the instrument light source and affect its emission properties, resulting in a failed calibration. It seems that this problem is more often seen in association with the i1Pro 2 than with the original i1Pro.

3- My instrument is connected but I cannot make a measurement. Can I fix this? There are two things to check: 1. Make sure you are not running, at the same time, two programs which access the same instrument. 2. PatchTool should be used with only one Eye-One/i1Pro/i1Pro 2 connected at a time and only one i1Pro 3 at a time. You can however connect one Eye-One/i1Pro/i1Pro 2 in addition to one i1Pro 3 and one i1Display Pro since these instruments use different drivers. All Datacolor Spyder models can be connected simultaneously except the Spyder4 and Spyder5 which share the same driver; the Spyders can also be connected in addition to X-Rite products. If the above checks do not apply, you can also try to disconnect and reconnect the instrument.

2- My i1 (Eye-One) is connected but not recognized by PatchTool. What can I do? You may receive a message to the effect that the i1 (Eye-One) is not connected when you click on the "Info" button of the Display-Check, Display-Reader, and Patch-Reader windows. Assuming that your instrument is indeed connected, first check if the i1Profiler program from X-Rite is opened, and, if opened, close it, since PatchTool cannot be used at the same time. Early versions of i1Profiler provide a control panel named “X-Rite Device Services”, which is used to assign/unassign instruments to X-Rite software. On a Mac, the “X-Rite Device Services” control panel is located in the System Preferences dialog. The latest versions of i1Profiler still include “X-Rite Device Services” but do not include a control panel, and instrument assignment is performed dynamically when opening an X-Rite program. If using an early version of i1Profiler, you should DESELECT the i1 (Eye-One) in the “X-Rite Device Services” control panel; this will make the instrument available for PatchTool. Please note that changes in the X-Rite control panel can be done while PatchTool is opened. You should then be able to connect the instrument by clicking on the "Info" button. The early versions of i1Profiler may also open one or more dialogs asking if you want PatchTool to take ownership of the i1 peripherals; please

1- What are the differences between PatchTool and CT&A? There are too many to list in a short answer! However, we can globally answer this question by looking at typical uses. If you are interested in comparing or converting a color from an RGB space or a color catalog (i.e. a Color Deck) to another RGB space or color catalog, then CT&A is a good choice. As well, if you want to transform your i1Pro or i1Pro 2 into a full-featured densitometer (see Density) or a powerful spectral analysis tool (see Color Rendering Index, FluoCheck, Graph, ISO 3664+, Metamerism Index, RAL Design, Whiteness), the answer is again CT&A. On the other hand, if you want to open, measure, edit and join color lists (in CGATS, spreadsheet, CxF, Adobe Swatch Exchange (ASE), or text formats), of any size, and view, convert, average, or compare them, then PatchTool is the solution. If you want to check your display performance against a reference color list or measure a display without constraints, and using many different instruments, then again PatchTool is the answer. These products complement each other; you could well use CT&A to assess a light booth illumination uniformity and light quality, then use PatchTool to average your printer or press calibration targets and check their accuracy relative to known reference values. Please consult the programs' features (CT&A, PatchTool) and their respective Help manuals for additional information.

12- (macOS Sierra) Why do I get this fatal error on program launch: “(EM-19) CT&A cannot open the ColorDecks database…” ? This question is applicable to CT&A Version 5.0 or OLDER packaged in a ZIP file (This section does not apply to CT&A 5.0 packaged in a disk image file, i.e. *.dmg). This can happen if CT&A was downloaded AFTER the installation of macOS Sierra AND if the Mac is not configured to accept applications downloaded from “Anywhere”. You will find more info on how to set the proper permissions in the Mac OS Compatibility page.

11- Are my CT&A Name and Key valid for both Mac AND Windows versions? For CT&A 5.x+, i.e. 5.x and and more recent versions, yes (and only the Key is required). With CT&A 5.x+, the Product Key can be used on either OS, one OS at a time. You will find more information in the “Software activation” section of this FAQ page. For CT&A 4.x and older versions, no. CT&A 4.x and older versions use different licensing systems for Mac and Windows versions. A license purchased for the Mac OS cannot be used with or transferred to a Windows OS, and vice-versa.

10- Can I make an ICC profile using CT&A? You can make matrix RGB profiles by specifying the chromaticity coordinates of three primaries, the chromaticity coordinates of an illuminant, and a gamma function. This is done with the Custom RGB space dialog of the RGB-vs-RGB tool. You cannot make RGB or CMYK profiles from measurements.

9- My i1Pro/i1Pro 2 is detected but I get an error message when I calibrate. What is wrong? Calibration failure more often occurs when calibrating in reflectance mode. This can happen even if the instrument is properly detected and identified in the 'Information info' dialog. Here are potential causes to look for: 1. The instrument is not properly seated on the calibration tile. This may seem obvious but it is worth checking! 2. The calibration tile is dirty. Clean it gently with a soft tissue lightly dabbed in isopropyl alcohol. 3. You are using the wrong calibration tile for the instrument. The i1Pro calibration tile is matched to the instrument at the factory.

If a connection is loose, you can sometimes improve it by pushing, holding, or reinserting the connector. Try another USB cable or another USB port to see if you get better results. In some extreme cases your computer USB port or your instrument connector may need to be replaced. 5. The overall USB cable resistance is too high. This can be due to a poor quality cable, a damaged cable, a cable which is too long, or a cable with dirty connectors. 6. The computer USB port cannot provide enough current for calibration. This is more often a problem with external USB hubs. Try a USB port which is not used (i.e. connected and disconnected) often. 7. If all of the above is non-conclusive, your instrument may be due for a factory calibration or repair.

If the overall cable plus connectors electrical resistance is too high, this will lower the actual voltage applied to the instrument light source and affect its emission properties, resulting in a failed calibration. It seems that this problem is more often seen in association with the i1Pro 2 than with the original i1Pro.

8- My instrument is connected but I cannot make a measurement. Can I fix this? There are two things to check: 1. Make sure you are not running, at the same time, two programs which access the same instrument. 2. CT&A should be used with only one Eye-One/i1Pro/i1Pro 2 connected at a time and only one i1Pro 3 at a time. You can however connect one Eye-One/i1Pro/i1Pro 2 in addition to one i1Pro 3 and one i1Display Pro since these instruments use different drivers. The Datacolor Spyder5 and SpyderX can be connected simultaneously, and in addition to X-Rite products. If the above checks do not apply, you can also try to disconnect and reconnect the instrument.

7- My i1 (Eye-One) is connected but not recognized by CT&A. What can I do? You may receive a message to the effect that the i1 (Eye-One) is not connected when you select the "Peripheral/Instrument info...” menu. Assuming that your instrument is indeed connected, first check if the i1Profiler program from X-Rite is opened, and, if opened, close it, since CT&A cannot be used at the same time. Early versions of i1Profiler provide a control panel named “X-Rite Device Services”, which is used to assign/unassign instruments to X-Rite software. On a Mac, the “X-Rite Device Services” control panel is located in the System Preferences dialog. The latest versions of i1Profiler still include “X-Rite Device Services” but do not include a control panel, and instrument assignment is performed dynamically when opening an X-Rite program. If using an early version of i1Profiler, you should DESELECT the i1 (Eye-One) in the “X-Rite Device Services” control panel; this will make the instrument available for CT&A. Please note that changes in the X-Rite control panel can be done while CT&A is opened. You should then be able to connect the instrument by selecting the "Peripheral/Instrument info...” menu once again. The early versions of i1Profiler may also open one or more dialogs asking if you want CT&A to take ownership of the i1 peripherals; please answer “Yes” to the question(s). “X-Rite Device Services” is dedicated to X-Rite programs and is not under CT&A's control; any problem related to its use should be directed to X-Rite. If the above fails, you can always try to disconnect and reconnect the instrument.

6- Is there anything I should know before measuring my display? As a matter of fact, yes! Many CT&A users measure their monitor or home cinema's color temperature, luminance, and chromaticity using either the program's RGB vs RGB or Graph tools, with the input data coming directly from an one of the supported instruments. We have thus prepared a tutorial on how to make and interpret these measurements (Tutorial 10: Measuring color patches on a display) which can be found in the program's Help manual, a PDF which is available as a separate download.

5- Can I use my eXact / FD-7 / Spectrocam instrument with CT&A? Currently, no. Click on the tool name in the following list to go to the specifications section dedicated to instruments support: RGB vs RGB tool, Munsell tools, spectral tools (CRI, Density, FluoCheck, Graph, ISO 3664+, Metamerism Index, RAL Design, Whiteness). Instrument support is based on user demand, the availability of software interface tools from the instrument companies, and how well the instrument features and functions match with CT&A.

4- Is a calibrated monitor required? No. Although strongly recommended, a calibrated monitor is not required since a lot of the data provided by the program is in numerical form. However, if your display is calibrated with an ICC profile, CT&A will detect the default display profile and show accurate colors since CT&A is color managed; this capability is useful for the patch layouts of the RGB vs RGB tool , for the Munsell tools, and for all spectral tools where patches are shown (Density, FluoCheck, Graph, Metamerism Index, RAL Design). The display profile can also be user-assigned.

3- Do you use the same gamma for all spaces? No. If a multi-parameter gamma is defined for a given space, sRGB or eciRGB_v2 for example, the higher accuracy multi- parameter definition is used by default. However, the user has the option of using a single parameter gamma if desired. The detailed parameters and the single value gamma are displayed in the menu-selectable Space data table. Note: The L* (L-star) gamma of eciRGB_v2 has, by definition, the same equations as the multi-parameter gamma of sRGB and NTSC, but with different values for each parameter.

2- What are the differences between PatchTool and CT&A? There are too many to list in a short answer! However, we can globally answer this question by looking at typical uses. If you are interested in comparing or converting a color from an RGB space or a color catalog (i.e. a Color Deck) to another RGB space or color catalog, then CT&A is a good choice. As well, if you want to transform your i1Pro or i1Pro 2 into a full-featured densitometer (see Density) or a powerful spectral analysis tool (see Color Rendering Index, FluoCheck, Graph, ISO 3664+, Metamerism Index, RAL Design, Whiteness), the answer is again CT&A. On the other hand, if you want to open, measure, edit and join color lists (in CGATS, spreadsheet, CxF, Adobe Swatch Exchange (ASE), or text formats), of any size, and view, convert, average, or compare them, then PatchTool is the solution. If you want to check your display performance against a reference color list or measure a display without constraints, and using many different instruments, then again PatchTool is the answer. These products complement each other; you could well use CT&A to assess a light booth illumination uniformity and light quality, then use PatchTool to average your printer or press calibration targets and check their accuracy relative to known reference values. Please consult the programs' features (CT&A, PatchTool) and their respective Help manuals for additional information.

1- Is the program name BabelColor, BabelColor CT&A or CT&A? (Updated - 2020/07) "BabelColor" is the name by which the program was known when it was first offered, more than 17 years ago. BabelColor is a registered trademark for color tools, products and services and should not be used to describe a single product. The program was later presented as "BabelColor Color Translator & Analyzer" as well as in a shorter form, "BabelColor CT&A". To further separate the company name from the product, we now usually refer to it simply as "CT&A".

8- Can I use CT&A or PatchTool in a virtual machine? You may receive this message when starting CT&A or PatchTool in Windows: “The function failed because this instance of your program is running inside a virtual machine / hypervisor and you’ve prevented the function from running inside a VM. The program will run in Trial mode.” This message indicates that your computer is configured to work in a Virtual Machine and that the CT&A or PatchTool licensing scheme is not configured to be used in this environment. In most cases this virtual machine (called Hyper-V) is enabled but not used; for instance, it can be automatically activated when installing “Visual Studio”. To disable this feature, type “Hyper-V” in the Windows search bar and look for the control panel to “Turn Windows features on or off”. Uncheck the following options, one at a time, rebooting after each change, and restarting CT&A or PatchTool to test: “Hyper-V Platform”, “Virtual Machine Platform”, “Windows Hypervisor Platform”, “Windows Defender Application Guard”. Please note that we have seen cases where two reboots were required to make a change effective. You should also check that Intel Virtualization Technology / Hypervisor is not enabled in your computer BIOS.

7- What information is sent to the license activation server? For software licensing purposes, the program (CT&A or PatchTool) generates a "fingerprint" to uniquely and anonymously identify your computer. The "Product Key" and the "fingerprint" are sent to an activation server which sends back an activation certificate. No personal data is used to generate the fingerprint. The activation server will also record network related data from where the request comes from.

6- I have a working Internet connection but activation fails. What can I do? You may need to unblock some specific communications ports used by the program. Activation requires that ports 80 and 443 be open. Please consult your company’s network specialist for help.

5- Is an Internet connection required to use CT&A or PatchTool? An Internet connection is not required once a Product Key is activated on a computer. An Internet connection is preferred to activate and deactivate a Product Key. However, if because of Company rules the computer on which CT&A or PatchTool is installed cannot be connected to the Internet, activation and deactivation can also be performed OFFLINE. Please note that a service fee is required for offline activation. This fee covers the time to manually process the request and set the activation server; it can be paid from the BabelColor purchase page. You should carefully read the activation and deactivation procedures are presented on this page if you are interested in, or if you must use, offline activation.

4- How can I transfer a software license between computers? This transfer requires deactivating a first computer and activating a second computer. The activation and deactivation procedures are presented on this page. These procedures can also be found in Section 1.3 of the CT&A Help manual and in Section 5.3 of the PatchTool Help manual.

3- Can more than one license be assigned to a Product Key? Yes. If many licenses are assigned to a key, then you can simultaneously activate many computers up to the number of licenses. Many licenses are typically assigned to a single Product Key when the same Product Key is used by one Company. Please contact BabelColor for more information and a quote.

2- Can I use my CT&A Product Key with PatchTool, and vice-versa? No, a Product Key can used to activate only the program for which it was purchased.

1- Is my Version 5.x, 6.x or 7.x Product Key valid for both Mac AND Windows versions? Yes, a CT&A Version 5.x or 6.x Product Key or a PatchTool Version 5.x to 7.x Product Key can be used for both Mac and Windows. Separate install files are available for each OS on the download page. Please note that the number of simultaneously activated computers depends on how many licenses are assigned to a Product Key. In most cases a single license is assigned to a Product Key; this means that only one computer can be activated at a given moment. However, you can transfer a license by deactivating a first computer and activating a second one; the activation and deactivation procedures are presented on this page.

8- (Mac) The application, an old version downloaded in a .sit archive, does not launch. What is the problem? This has been noted with archives saved in the "Stuffit" format (*.sit), which was used only for the older CT&A versions dedicated for the Mac Classic OS; the latest software releases are compressed in the .zip archive format, for which this is not an issue. The problem is very likely caused by the Stuffit program on your Mac; more specifically, the application may not be set with the proper permissions after being un-stuffed. The problem happens in particular on computers which have been upgraded from OS 9 to OS X, or on which Stuffit 8.0 was installed previously. Here is something from the Stuffit site: "StuffIt Deluxe 8.0 caused a problem whereby applications would not run if they were expanded from archive formats that do not preserve UNIX file permissions. In earlier versions of StuffIt Expander, this problem did not occur because the UNIX "execute" permission was set on all files as they were expanded. StuffIt Deluxe 8.0.2 restores that feature. However, if you are certain that you do not want the "execute" permissions set, you can tell StuffIt Expander not to alter UNIX file permissions when expanding non-UNIX compatible file formats. This can be done in StuffIt Expander preferences by un-checking the box that says "Set execute permissions by default". " You can try this to fix the problem (also from Stuffit makers): "Troubleshooting for all Mac OS X products: Disk Repair and Permissions Repair If you are experiencing problems with any of our software that runs on Mac OS X (or any other Mac OS X compatible software for that matter), please try the following general fixes and maintenance: Disk and Permissions issues: It is possible there is a problem with your disk and/or disk permissions. There are easy steps to attempt a repair of such issues provided as part of your Operating System. Boot up from your OS X CD and run the "Disk Utility" program. Select the "First Aid" tab, select your hard disk and click the "Repair Disk" button. Once it is finished, if errors were found and repaired, run "Repair Disk" again until it runs cleanly once without reporting any errors. Now boot up from your startup drive and launch the "Disk Utility" program. Select the "First Aid" tab, select you hard disk and click the "Repair Disk Permissions" button. "Repair Disk Permissions" is an important step and Apple recommends that it be run periodically. When it is finished reboot from your startup drive." You can also change the application permissions using the Info window (ctrl + mouse click on the program icon, then select "Get Info"). Here is what the settings should be: o Ownership & permissions: Read and Write o Details/Owner: Read & Write o Details/Group: Read only o Details/Others: Read only And finally, you can change the permissions using the "sudo chmod" Terminal command (the command is a short form for "SuperUser ChangeMod"), and is used as shown below for BabelColor CT&A (for PatchTool, replace "BabelColor CT&A.app" by "PatchTool.app"): $ sudo chmod 755 BabelColor CT&A.app From "Mac OS X: the Missing Manual": "The chmod command is a quick way to change access privileges-including Execute permission, which isn't available in the File Get Info window. The 755 business is a long story, which you can read at any Terminal prompt by typing man chmod and hitting Enter. In short, however, this code is shorthand for "Change the permissions so that everyone can read and execute (but not make changes to) this file"-just what you want for a CGI script. After hitting Enter, you're ready to proceed. Now sudo asks for your administrator's password. Once you've entered it, press Enter.."

7- (Mac) The Console shows that the hasplmd process is crashing every 10 seconds. Can I stop it? This problem has been seen in Mac Lion (OS X 10.7), Mountain Lion (OS X 10.8), Mavericks (OS X 10.9), and Yosemite (OS X 10.10). The hasplmd process is a license manager program used with USB security keys, or "dongles". The problem has nothing to do with BabelColor software but may be due do to an older X-Rite software component installed to support the i1Display Pro. We have noted that the problem comes back whenever we install a new version of i1Profiler. Please consult the Mac OS X Compatibility page on this site for more information on how to identify the problem and fix it.

6- (Mac) I updated the Mac OS and I am asked to install Java SE 6 runtime. Is this OK? Yes. This message may appear at reboot after updating your Mac OS, when you start PatchTool's Display-Check or Display- Reader, or when you select the DTP94 instrument in these tools. Although PatchTool is not programmed using Java code, it looks like the DTP94 library requires it. Please consult the Mac OS Compatibility page on this site for more information on the problem and how to fix it.

5- (Mac) I get a message that CT&A or PatchTool is from an "unidentified developer." What can I do? This question is applicable to: • CT&A: Version 5.0 or OLDER packaged in a ZIP file (This section does not apply to CT&A 5.0 packaged in a disk image file, i.e. *.dmg) • PatchTool: Version 5.0 or OLDER (This question does not apply do PatchTool 5.1) This is a message which appears in recent Mac OS versions, starting with OS X 10.7 (Lion), for programs not downloaded from the Apple App Store, or for programs created by developers which did not pay to be "identified" by Apple. IMPORTANT: If you are using macOS Sierra (10.12), you may need to change the Gatekeeper settings BEFORE you download CT&A or PatchTool. You will find more info in the Mac OS Compatibility page on this site.

4- (Mac) Is your software compatible with PowerPC? The most recent versions of CT&A and PatchTool for Mac are not compatible with PowerPC computers and are offered only in packages for Mac-Intel computers. However, PowerPC packages may have been provided in a previous version; please consult our download page for availability.

3- (Windows on Mac) Can I use your Software for Windows on a Mac? This answer applies to CT&A and PatchTool Version 4.x or less since, for Version 5.x of both programs, a Product Key can be used on either OS. Some customers successfully tested the Windows versions of BabelColor Software on Macs configured for dual Mac/Windows boot. However, since it is very difficult to test all combinations of hardware and OS on the market, including the various regional settings, there are certainly issues that we are unaware of. Please note that our Windows Software was not designed for, nor tested with, Virtual PC and other Windows emulators, since there are native Mac versions available. We have received feedback from users to the effect that CT&A for Windows does not launch properly on older versions of Virtual PC; we do nonetheless appreciate feedback on your experiments with our software on emulators.

2- (Windows) The program does not behave properly after installation. What can I do? This answer applies to CT&A and PatchTool, Version 4.x or less. If you have a problem starting the program or with registration, please use the following procedure: • Disable any anti-virus program • Uninstall the program • Reboot the computer • Disable any anti-virus program • Check that the application folder you just uninstalled is empty. The default application folder path is: "C:\Program Files\BabelColor\PatchTool\" or "C:\Program Files\BabelColor\CT&A\" or, if using a 64-bit OS: "C:\Program Files (x86)\BabelColor\PatchTool\" or "C:\Program Files (x86)\BabelColor\CT&A\" Trash any files in this folder if required. • Install the program • Launch the program and enter your registration Name and Key. Please consult Question-1 above if you are asked to re- enter your registration info

1- (Windows) The program always asks to re-enter the registration info. How can I fix this? This answer applies to CT&A and PatchTool, Version 4.x or less. In some circumstances, when being launched, the program may show a message indicating that the copy is not registered, even if you previously successfully entered your registration Name and Key. When this happens, you should launch the program as an administrator, and re-enter the registration info (you can do a right-click on the PatchTool or CT&A icon and select "Run as administrator" from the popup menu). Once you have entered the registration info in such a way, you should be able to start the program normally thereafter. Please contact us if the above suggestion does not work.

9- (Linux) Are there Linux versions of your Software? No. Linux versions are not planned for the moment.

6- Will I be able to get free upgrades? Yes. Your license is valid for all incremental upgrades (x.1, x.2, etc.). Your exclusive permanent license code will not need to be updated for these upgrades. However, upgrades to a major revision, from 5.x to 6.x for example, may require additional purchasing, although rebates for owners of the previous version will be available for a limited time after product launch.

2- Is BabelColor Software shareware? Yes, as per one of the numerous interpretations of the term!. You can give a copy to a friend or colleague as long as you give the complete evaluation package. Of course, if you purchase a BabelColor Software, you cannot give or lend your license. Also, you cannot distribute or offer for download the evaluation package unless you have a written agreement with BabelColor.

1- Can I get evaluation copies of BabelColor Software? Yes. There is no need to buy a license to download and install our programs. Please note that, without a license, the program will operate in demo mode, with limited capabilities. However, this should enable you to do basic measurements with many tools (CT&A), open all compatible files (PatchTool), or have access to PatchTool’s free tools (Custom Illuminants, Extract Data from Profile, CT&A Export). If you want to access all the programs' features, you need to purchase a license.
