Step 2. Create association of Prometeus with DAX files

It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the DAX file with the Prometeus application.

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the DAX file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our DAX file. As a result of the scan, sometimes it is not possible to recover DAX files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the DAX 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular DAX file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted DAX files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
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. It is best to move DAX to a different directory.
This can happen on a file that does not support multiple access. In this case, the DAX file is blocked by the first application to open it. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the DAX file again. Some anti-virus or backup software may occupy the DAX file for a certain period of time. If nothing helps, please reset the device.
