However, to the best of my knowledge, the license keys for Windows 7 and up (I am not sure about Vista) work for both 32-bit and 64-bit install media: all you'd have to do is get a copy of the 64-bit setup disc (which I seem to recall hearing can be downloaded from Microsoft's website) for your Windows version, backup your data, install the 64-bit version and enter your current license key.
Pretty much any machine new enough to run MWO will have a 64-bit CPU.
It's just a matter of installing a 64-bit version of Windows.
