Visual Studio 2010 SP1 beta install failed, now won't uninstall

Against the advice of one of my buddies, I installed the Visual Studio 2010 SP1 beta on my dev box at work. Or rather, I tried to. I used the web installer, but halfway through the install it failed.

When I try to uninstall or repair it, I keep getting dialogs saying that different files aren't available and I need to insert various CDs. Trying to do a fresh install from the ISO version yields the same result.

Any suggestions?

Edit: I'm run开发者_如何学Goning Windows 7 64 bit. The files seem to be different every time I try to repair or uninstall the SP, but last time the dialog was asking me to insert the visual studio 2010 prerequisites disk. Another time it was complaining about the F# runtime. I'll try again and post a few specific file names, but I don't think the files are the issue so much as the botched install.

Figured it out. The installer was looking for files in my Temp directory, since that's where the web installer initially put them. It was still looking there, even when I was running the ISO installer. Every time the dialog popped up, I was able to browse to the file on the ISO. It would ask for the file again, and then it would accept it. Very strange, but it eventually worked. The reapplication took about an hour to complete. Hope this helps someone else!
