How to open MII file?

An often recurring problem with Wii Virtual Avatar Format is that MII is not associated with the correct program file. Thus, when you open MII, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MII 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 My Avatar Editor

Programs to open MII file

Remember to download programs supporting MII files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of My Avatar Editor with MII files

If the application is or has been freshly installed, but the MII file still does not use the My Avatar Editor program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting 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 My Avatar Editor application as the default for handling the MII file.

Step 3. Update My Avatar Editor to the latest version

The fault may also lie with the My Avatar Editor program, it is possible that Wii Virtual Avatar Format requires a newer version of the program.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the MII file. 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 virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file MII or the program directory. Sometimes virus-infected MII files cannot be recovered, so make a backup in advance.
Older version of MII file may not always be supported by the latest software version. 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. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair MII file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted MII 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. While there is usually no problem reading such a file, it may not be possible to save it. Copying the MII file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file MII to close. 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.
