Windows 7 Upgrade - Product Key Issue
A couple of years ago I purchased a Windows 7 Upgrade DVD and License to upgrade my Vista machine. That went fine, but I needed to carry out a clean reinstall of the OS onto the upgraded laptop. It all went well until I was asked for the Product Key, which I have and I entered - it failed.
Having carried out some research, it is obvious now that I cannot do this because it is expecting an old version of the OS to upgrade. Is there some way that I can retro-fit this (I cannot reinstall Vista as it was OEM)? I am happy to buy a licence if need be, but I hope that thare is a cheaper way around it.
