Who said I have just 1 copy of enterprise? The DVD I was talking about is our volume licensed one. I was planning on using KMS (which also wasn't very usable when I last tried it) to manage all the licenses.

To Rifleman:
I didn't type what I was thinking...I meant I usually got that denied error when trying to download to the root of C. I got it with UAC on and off. Before the first SP UAC was the first thing I disabled. The service pack made it quite a bit better, at least in my opinion.
