As long as you still have the Windows 7 Professional product key you'll be okay. The key will work for either the 32 bit or the 64 bit versions of Professional.

REMEMBER, only ONE INSTALL per product key though!

You can download the Windows 7 Professional x64 version from this link:
Windows 7 Professional x64 ISO http://msft-dnl.digitalrivercontent..../X15-65805.iso

The ISO image is 3.02 GB in size. Save it to a folder or somewhere where you can remember where it is. Then use ImgBurn or another ISO burning program to burn the ISO image to a blank DVD at no faster than 4x burning speed. (This is to avoid any burning errors.) Then use the burning program to verify the burned DVD against the ISO image just to be sure it's all good.

You'll have to do a clean install though, because it is not possible to "upgraded" from a x86 (32bit) install to an x64 (64bit) install.

Be sure to download ahead of time all the 64 bit drivers for your computer and store them on a thumb drive, external hard drive or burn to a CD-RW disk.
