I received Win 7 retail (£109) as a gift and assumed it was for 3 pc's because it's retail. (After searching net now it appears this isn't the price of a 3 pc o/s.)
I have installed this on my g/f's laptop - clean install & activated. I then installed it on my main pc which already had Vista 64 (not a clean install). Obviously I'm being prompted to enter the product key and it's not accepted.
Will I need to purchase another retail copy of Win. 7 or will the upgrade edition be ok? I'm a bit ###### off because we would happilly have paid the £150 for the 3 pack.
