I dunno, that's a lot of individual fixes (Reg files) to apply if *every* association on your PC is fouled up. Would it be easier to just run System Restore back to before you upgraded Adobe Suite? Then you can try upgrading it again to see whether it breaks all file associations every time out.
I'm not an IT guy, and I don't even play one on TV. Just guesswork on my part.
Sigh, with me, I've upgraded my Counterspy software and now about every other time I turn my PC on I can't get to the Vista login screen. Bah.
