Troubleshooting MUI Files

We usually associate the inability to open and work with a MUI file with the fact that we do not have the appropriate software installed on our computer. However, other problems may occur that block the ability to work with the file. The following list presents some of those drawbacks that we can normally find with this type of file.

  • Wrong .mui file associations in the Windows registry system: It may be the case that we install new software that asks us to associate certain types of files. By doing this, we may lose the original association registry for a .mui file.
  • Removing the .mui extension description from the Windows registry: This problem is rare but common among so-called "geeks" who modify, add, and delete Windows registries at will. To solve it, simply create the registry again with its original name and values.
  • Incomplete installation of an application that supports the MUI format: complementing the two previous items, a faulty or abruptly interrupted installation can damage or corrupt Windows registries, preventing the correct opening and use of .mui files.
