Step 2. Create association of Calamus SL with CDK files

If, despite the installed application, the CDK file does not start in the Calamus SL application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. 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.

The fault may also lie with the Calamus SL program, it is possible that Calamus SL Document requires a newer version of the program. In this case, use the invers Software website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the CDK file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file CDK or the program directory. Sometimes virus-infected CDK files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the CDK file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular CDK file corruption. The easiest way to restore the file is from a backup or by contacting N/A, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted CDK files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. Copying the CDK file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file CDK to close. However, some background programs may block the CDK file while scanning. If nothing helps, please reset the device.
