When you run an application that uses audio recording or playback functionality in Windows Vista, you may receive an error message that states that a file or a Microsoft Windows component is missing or could not be started.

For example, when you click Mixer in Windows Media Encoder 9, you receive the following error message:

The mixer application ’sndvol32.exe’ could not be started.
The system cannot find the file specified. (0×80070002)

Note: The specific error message that you receive depends on the application.

After you upgrade an earlier version of Windows to Windows Vista, some files appear to be missing. For example, the files in the My Music folder may appear to be missing.
