if you have windows 7 RC, then your build is 7100. change that line from 7233 to 7100, and it will allow you to perform an upgrade
give it a shot, see how it goes.
So how would I go by doing this? Just copy the files from the CD to my HD and edit the files, then reburn it? Or can I install it from the HD? How about a thumbdrive?
