I have Windows 7 RC installed on my laptop. When I upgraded from Vista, IE8 was included in the install. IE started to act up, would not start, etc. I uninstalled it and now I can't reinstall it. I have tried IE8, 7, & 6. They all say the same thing when I try to install them, "This version of Internet Explorer is not compatible with this version of operating system". Microsoft doesn't make a version of IE that is compatible with their own OS? Any ideas? I usually use Firefox, but I need IE for some programs at work. Thanks.
