Windows 7 license - move from 32bit to 64bit with OEM key with Lenovo [duplicate]

Can I use a Windows 7 Professional 32-Bit OEM licence to install the 64-Bit version, too?

"I know of people who have done this with ASUS branded laptops.

I don't see why it would be any different for any other brand.

I'm pretty sure the key is tied to the product version not down to the 32/64 bit version. As long as you install the same version, ie., Upgrade from Windows Home Premium 32bit to
Windows Home Premium 64bit you should be ok."

"Trip Report:

New latptop came with Windows 7 pro 32bit installed.

I went through this guide and it was pretty accurate.

Make backups of the supplied swtools folder with all the drivers and programe.
Used the ABR utility (Activation Backup and Restore) to extract the windows authentication tokens
Ripped an ISO of my Windows 7 Home Premium disc
Used this eicfg utility to edit the ISO so it will show a menu to let me select which version of Windows 7
Installed Windows 7 Pro 64 bit, but I didn't type in my product key
Use the ABR utility again to active my new 64bit OS
Installed Thinkvantage update utility to get all my drivers back."
