HAHAHAHAHA. Before I posted I tried opening in winzip but I didn't think of trying 7-zip and I didn't see that 7-zip was used while searching the forums. So after I posted I then spent a half hour moving the entire documents and settings folder to the D drive & playing in the registry, which seems to have worked in a very pain in the neck kinda way. I decided to come check this topic while the installer was going now that it had enough HD space and post my solution in case anyone else needed it. Turns out I should have just waited around since bovi provided a much much easier answer. Oh well, at least I won't have this problem with any future software I guess.

Thank you for the reply though, especially so quickly. Nice to know it's possible to get accurate tech help even as I'm bumbling around with my own overkill solutions.
