Just re-installed my bought copy of Windows 7 but need to activate it and I can't find the box with the product key. I tried Belarc Advisor but not sure where to look for the key with that. Tried Magical Jelly Bean Keyfinder - but get the following message when I try to input the key that gives me:
"The product key you have entered appears to be a default product key and cannot be used for activation. Type a different Windows 7 Home Premium product key."
Any advice please?
