You can also check that the required filter is registered correctly by navigating to the following registry branch:
HKEY_CLASSES_ROOT\CLSID\{17CCA71B-ECD7-11D0-B908-00A0C9223196}\InprocServer32
If any part of the path is missing then you've got issues, the nearer the start the greater the issue and possibly a miracle but anyways, that is the important path to the information that I'm assume to be missing, invalid or corrupt.
