I recently did a clean install of Windows 7 and am now trying to install Office 2007. The 2007 disk I have is an upgrade disk, and I have the 2003 disk. I don't think that has to do with the problem though, because when I try to install Office 2007, it asks me for the 2003 copy, which I put into my other CD drive, then goes ahead and I start it installing. It waits a little bit then, and a message comes up saying that "Setup cannot find Office.en-us\osetupui.dll. Browse to a valid installation source, and then click OK." If I browse and select the CD drive in which the 2007 CD is in, the same message pops up again asking for a different file in Office.en-us and if I keep doing that, it asks for more files and eventually starts asking for the same files, so it obviously isn't finding them.
I've tried running the setup off the HD, using a different Office 2003 CD (one was professional and the other was basic), and I've tried installing 2003 fully, but with the same result.
What can I do to fix this?
