SYMPTOMS
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. (0x80070002)

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



CAUSE
This issue occurs because some older applications use files or components that were developed before Windows Vista. The names of these audio components may be different in Windows Vista. If the calling application uses hard-coded file names, the new files and components cannot be located.

For example, Windows Media Encoder 9 tries to start Sndvol32.exe. In Windows Vista, this component is named Sndvol.exe. Therefore, Windows Media Encoder 9 cannot locate the file, and you receive the error message that is mentioned in the &quot;Symptoms&quot; section.
