    You can't upgrade between 32bit and 64bit. You have to do a clean install of Windows 64bit. Check out this Tutorial.

    Normally a Retail Upgrade version of Windows 7 comes with both 32bit and 64bit disks and one key that will work for either one. What do you have??

    It should work unless it is an OEM version but not sure if those keys are locked to 32bit. Retail version is fine. Where did you get your disk and is it Retail or OEM???

    As stated, you cannot upgrade from the 32-bit version of Windows 7 to the 64-bit version. It has to be a clean install.

    However, if you have a 64-bit upgrade DVD you can use that to carry out a clean install.
