Nah thats not the problem, u can installnit multiple times, the problem is 1 at the install, it say that the key is invalid, soni took generic one off the internet. so after it installed, i went to change the code, but it said this product key must be used on an upgrade only, hence i need the retail one
Ibviously cause i got the bad code online, windows picked up on it and now its all 'ungenuine' in my face :P
