Windows 7: install says my product key is invalid

Unholyist,
I think setup does check for a windows installation when setup first starts. You can still format or delete that partition within setup to have a nice clean blank PC for win7, but this is treated differently than installing to a completely blank non-partitioned drive. Please see my posting here:

Talk about dumb, and a waste of time. I just had the same thing. I installed the student download version of Home Premium onto a Laptop that had Vista, but whose drive had failed. So the laptop had a new, blank drive.

The product key failed.

I had to reboot from the DVD, delete the already installed Win 7 partition, and install it again. Then the product key was accepted.

Thanks to above for the instructions as to how to get around this annoyance.

Run a Repair install from the new desktop. A repair install is an upgrade over itself in Win7. This will make the installer think there is a previous qualifying OS and allow you to insert the key.

Otherwise wait til after intsalll and insert key at Computer>Properties link.
