I had beta 1 of IE 7.0 and I dowloaded beta 2. When I tried to install it I got a message saying to uninstall the old version in the add/remove programs. IE wasn't listed so I tried to delete the actual files. I got rid of most of them but some said they were still in use. Now I can neither open or install beta 2 or IE 6 because it's an "older version" and I can't find beta 1 anywhere. The only reason I'm even using IE is because of a program I have to use for home work assignments. Any ideas?
