What is MUI file?

The MUI file has been categorized as System Files. The creator of this file is Microsoft. System Files consists of 323 similar files. Multilingual User Interface Format appears on 1 operating systems as a functional file. The file will work on Windows systems, unfortunately not on others. There are also 1 alternative programs to handle the MUI file. The Microsoft Windows programs will also handle the file when the Windows Multilingual User Interface program does not fulfill its role.

How to open MUI file?

The most common problem when using Multilingual User Interface Format is that a specific MUI is not associated with the program. Thus, when you open MUI, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the MUI file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Windows Multilingual User Interface

In this case, you should first verify that the Windows Multilingual User Interface application is installed on the computer. This can be achieved by typing Windows Multilingual User Interface into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file MUI.

Step 2. Create association of Windows Multilingual User Interface with MUI files

However, it may happen that the application itself does not cause the MUI file to open in the Windows Multilingual User Interface application, but you can set it manually. 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. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the MUI file with the Windows Multilingual User Interface application.

Step 3. Update Windows Multilingual User Interface to the latest version

If, however, after binding Windows Multilingual User Interface with Multilingual User Interface Format there were still problems, you should update the program to the latest version.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The MUI file may be unusually small compared to the original file. This is most often caused by a problem while downloading the MUI file. Downloading the file again should fix the problem.
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. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the MUI file that we want to open. Sometimes virus-infected MUI files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the MUI files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged MUI files.
The program indicates that the file is encrypted or corrupted. The encrypted MUI files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
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 MUI to a different directory.
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. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
