Step 2. Create association of VLC media player with ASX files

If, despite the installed application, the ASX file does not start in the VLC media player 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. 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. The "always use the selected program ..." field will set the VLC media player application as the default for handling the ASX file.

Step 3. Update VLC media player to the latest version

If, however, after binding VLC media player with Microsoft Advanced Streaming Redirector Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the VideoLAN Project Team website and install the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The ASX file may be unusually small compared to the original file. This suggests truncating the ASX file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. 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 ASX or the program directory. However, remember that not every infected ASX file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the ASX file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular ASX file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft
The program indicates that the file is encrypted or corrupted. The encrypted ASX 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. It is best to move ASX to a different directory.
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. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the ASX file for a certain period of time. If the problem persists, restart the machine.
