Vista business to windows 7??

OEM copy will be tied only to the computer you've installed it on - you can reinstall it whenever you like, but you can't install it on a different computer.

If you already own Windows Vista then get the upgrade version of Windows 7. You can still do a full, clean reinstall using your upgrade license so don't worry about that. In fact, moving between 32-bit and 64-bit systems usually requires a clean reinstall anyway.

Just make sure you've backed up everything you want to keep before you format your drive.

upgrade media is what you need and you are going to 64 bit so you will need a clean install!
