Other possible reasons why your .MUI file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .MUI file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .MUI file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .MUI file, so download the update and check again.

2. Incorrect .MUI file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

  • Right-click the .MUI file
  • Go to the "Open with" - then "Choose default program ..."
  • Locate the appropriate application
  • Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
