I've had similar problems before that I've fixed with IEFix
, which tries to reinstall some core IE files. I believe IEFix was originally designed for Windows 98 because running it on my XP computer, it asked for the location of a few files to reinstall that I had no copy of. Googling the files revealed that they were 98-era files. However, you can just cancel the browse dialog and it will skip over those files.
