Just for the record. I also have a "Upgrade Only" Academic version of Visa 32bit. I can do a fresh install. When I follow up with the Upgrade step so I can activate it, it hangs every time at the "Completing upgrade" step. I have found no solution for this. This is using the Vista DVD, not vLite. I'm actually here because a forum moderator sent me here to attempt a Vlite version with drivers built into the install as a potential solution. I can't disable my DVD as a test because I need the DVD to do the install.
