Class Not Registered (0x80040154): Why the Usual Fix Fails

I cannot believe that the fix was so easy after I had spent a great deal of time going around in ever decreasing circles...

Thank you so much for such an easy fix.

I can't believe it was THAT simple! After hours of pissing about with codecs and dxdiag tests and who know's what. Brilliant thanks.

downloaded/installed directx, registered as directed above. still getting "class not registered".

I got the successfully registered message but the error persists. It's the AVS DVD Player (a free version) that is now hard to find.

Thank u so much. It worked..

Quartz dll failed to load. Something to do with binary. Tried to get info copied but would not paste here
