in the iso, sources folder there is a file called cversion.ini
content of the file in RTM version looks like this
only part that actually matters is MinClient=7233.0, this basically means that any build older then 7233 can't perform upgrade.
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.
