What is KXX file?

The file with the extension KXX is the Misc Files file type. It was designed by Tavultesoft. Additionally, the Misc Files category contains 6033 of other files. Custom Keyman Engine Product is most often found on 1 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is Keyman Developer. This was created by Tavultesoft.

How to open KXX file?

The main problem with Custom Keyman Engine Product is that the KXX file is incorrectly associated with programs. Thus, when you open KXX, 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 KXX 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

In this case, you should first verify that the Keyman Developer application is installed on the computer. To do this, enter the name Keyman Developer into the system search engine. 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 KXX.

Programs to open KXX file

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

Step 2. Create association of Keyman Developer with KXX files

If the application is or has been freshly installed, but the KXX file still does not use the Keyman Developer program, it means no association. 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 set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the KXX file with the Keyman Developer program.

Step 3. Update Keyman Developer to the latest version

If, despite the association of the Keyman Developer program with the Custom Keyman Engine Product file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Tavultesoft website and install the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The KXX file may be unusually small compared to the original file. Usually this applies to KXX files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file KXX or the program directory. Sometimes virus-infected KXX files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the KXX files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular KXX file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Tavultesoft
The program indicates that the file is encrypted or corrupted. The encrypted KXX 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the KXX file to another location.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
