I have XP Pro 32bit and ordered the windows 7 64bit Home Premium Upgrade. Will I be able to upgrade it or should I cancel the order and order a Windows 7 64bit OEM? I should also mention that when I preordered the Windows 7 Upgrade the plan was to buy a new hard drive, reinstall XP 32 bit Pro on it and then install the Windows 7 64 bit upgrade. Can this not be accomplished?
