I have the same problem after doing an XP install-repair! I changed out my motherboard, and of course XP thinks it’s in a different machine, so I had to install-repair XP.
I got nearly everything back, except that AE6.5 gives me the same error you describe. It’s really irksome!!
If I delete the bad file, or just acknowledge the error, will it impact the ability to import/export AVI files?
I’d really like to solve this instead!
Thanks
