I brought win 7 family pack downloaded from microsoft. Windows 7 home Premium full not upgrade. Created iso disks 32bit and 64bit. Have product keys for both. The 64 bit disk is broke went onto my account at microsoft store not in purchase history. How can I download a copy of windows 7 that will work with my product key. Clicked on a link on these forums, downloaded and installed but it says key invailed. Have not put key etc on forum dont know if should or not. First ever post on a forum learning all the time.
