I am using Microsoft Office XP Developer to customize
web parts. It was
working fine till yesterday, but suddenly it starts to
give me an error saying "The query cannot be
completed, because of the error ((0x8007007e); The
specified module could not be found.", when I am
trying to open the files from web folder.

The same error pops up even when I try to open the web
folder from explorer. Has anyone encountered the same
problem?
