Hello, when Microsoft had the promotion on discount to upgrade to Windows 8 a few months back I was issued a upgrade key. I installed Windows 8 but then reformatted and reinstalled Windows 7. My question is, how can I install windows 8 using this key again. When I run the upgrade assistant it says the key is not valid. Is there a way I can use this key for a clean install? Thanks.
