Trust no one to do it correctly.
You can install 32 bit windows on a 64 bit machine. Go to Properties on the My Computer Icon. (This one, you are probably stuck with. A upgrade would be a full OS install)
Same goes for Calibre. Does it say [64Bit] in the version message on the bottom status bar? You have to have a 64bit OS installed to do this.
