How to open KCT file?

The most common problem when using Keyman Developer Customization Source is that a specific KCT is not associated with the program. Thus, when you open KCT, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the KCT file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Keyman Developer

The first step is to check if the computer has the Keyman Developer program installed. The easiest method is to use the system search engine by entering the program name Keyman Developer in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file KCT.

Programs to open KCT file

Remember to download programs supporting KCT files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Keyman Developer with KCT files

However, it may happen that the application itself does not cause the KCT file to open in the Keyman Developer application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the KCT file with the Keyman Developer application.

Step 3. Update Keyman Developer to the latest version

The fault may also lie with the Keyman Developer program, it is possible that Keyman Developer Customization Source requires a newer version of the program. In this case, use the Tavultesoft website or update the program from the application.

Step 4. Check for the following problems with the KCT file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the KCT file. The only repair option is to download the file again.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our KCT file. However, remember that not every infected KCT file can be recovered, so it is important to take care of regular backups.
Older version of KCT file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair KCT file corruption. You can restore the file from a backup or use Tavultesoft help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted KCT files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the KCT file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file KCT to close. Some anti-virus or backup software may occupy the KCT file for a certain period of time. If this does not work either, restart the device.
