Acrobat "Application Failed to Load its Core DLL"

Hello,

I'm having a problem with a single machine running Acrobat 7 Std that was bundled with MS Office Basic on a Dell Optiplex. XP SP2, 1 GB RAM, specs should be ok.

The user keeps getting the error "Application Failed to Load its Core DLL". A restart will temporarily fix the issue but it comes back. All updated have been applied.

Any ideas?

THANKS!!!
