Windows 8 Pro upgrade: how to switch from 32-bit to 64-bit
I have Windows 8 Pro 32-bit in a dual-boot configuration with Windows 7 Pro. Win8 was upgrade (DVD) from XP. At the time of upgrading I tried to install the 64-bit Win8 but the installer refused because my XP was 32-bit. I setted for 32-bit at the time.
Is there any way I can change to 64-bit (using the upgrade DVD) to move to a 64-bit path for Win8<.1>?
