Use the 64Bit disk to install 64Bit Windows 7.

You'll have to do a clean install of Windows 7 x64. You can do an upgrade, but its best to do a clean install for the best performance.

However, it must be done as a clean install rather than the upgrade. Just re-format the partition during the install process and you should be good to go.

You cannot upgrade from a 32Bit version to a 64Bit.
You cannot upgrade from Windows XP to Windows 7.

You can only upgrade from Windows Vista to Windows 7.
A clean install is required for Windows XP to Windows 7
A clean install is required to convert from 32Bit to 64Bit.
