SYMPTOMS
If you uninstall music programs that play Musical Instrument Digital Interface (MIDI) files, and then browse to a Web page that has embedded MIDI sound, the audio from the MIDI files may not play.
CAUSE
When music programs install, they may change the Content Type values for the .mid or .midi files, or they may use their own Content Type for these files. If the music programs are uninstalled, the original Content Type may not be restored to the default.
WORKAROUND
To work around this issue, do the following:
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
- Start Registry Editor (Regedit.exe).
- Locate the Content Type value under the following key in the registry:
HKEY_CLASSES_ROOT\.mid
- Double-click the Content Type value. For the Value Data, type the following:
Click OK.
audio/mid
- Repeat the process for the HKEY_CLASSES_ROOT\.midi registry key, using the audio/mid value.
- Quit Registry Editor.
MORE INFORMATION
