The correct title of this article is ffdshow.ax Exception. The initial letter is capitalized due to technical restrictions.
Problem: The player crashes with an exception pointing to ffdshow.ax when you open video files.
Solution: Sometimes, FFDShow or packs that install it will "forget" a ffdshow.ax file somewhere on your computer. A common problem when you have this issue is the player crashing with an exception pointing to ffdshow.ax. To get rid of the old ffdshow, you have to find it, unregister it and delete it. Like so:
- Go to Start -> Find -> Files or folders...
- Search for ffdshow.ax on your local harddrives.
- If you find it anywhere else than in your Program Files\Combined Community Codec Pack\Filters directory, take note of the full path.
- Go to Start -> Run... and type regsvr32 /u "X:\path\somewhere\ffdshow.ax" - of course substituting the path for the one on your computer. Note that if ffdshow.ax is in your WinNT\system32 directory, you don't need to specify the path (ie, just type regsvr32 /u ffdshow.ax).
- Now delete the ffdshow.ax file.
- If you found multiple ffdshow.ax's outside your CCCP\Filters directory, repeat these instructions once for each file.
- Playback should now work.
