Windows XP Media Ed.

[joe43wv]

I was creating an nlite iso of a Windows XP Media Ed. for a computer I was building, I had it automatically input the produt key, install drivers, and install SP3, I was testing the image on my virutal machine before I put it to DVD to make sure all the bugs are worked out before making the DVD. The problem I'm having is when it gets to the point of where it asks for the product key it gives me an error saying, "Invalid Product Key". I double checked the product key and it was typed in correctly, I tried remaking the image w/o SP3 and still the same result. Any ideas?
