Issues Opening Media Files


When I try to open various files (e.g. photos, videos, or voicemail/audio files) I receive an error message:

Class not registered.


The native programs for handling media files are occasionally updated by Microsoft and can reset the association in Windows, leaving it unable to open the files.
