Okay - I reinstalled the oem win 7 home premium to my system partition and formatted my primary partition. Then I reinstalled win 7 enterprise to the primary partition (now it dual boots for some reason, done this 15 times before without that happening??) and reinstalled all the drivers from the dell resource media cd. I was receiving this same error during the OS installation when it restarts itself. Also - the drivers are all extracting to the system partition, even though I'm running the win7 enterprise from the primary partition?
Anyways, I was finally able to create the zip file....
