Will my Windows 7 Pro 64-bit product key work with Windows 7 Pro 32-bit as well?

MJKeller asked on
Hello, I recently purchased a copy of Windows 7 Professional 64-bit from the university I attend. According to the Windows Upgrade adviser my laptop (Vista Business 32-bit) would be fully compatible with either 32-bit or 64-bit Windows 7. I installed the 64-bit only to find that around half of my drivers are incompatible and I need to install the 32-bit edition. To avoid having to buy a whole new copy, my question is will the product key that came with my copy of Windows 7 Pro 64-bit also work on a copy of Windows 7 Pro 32-bit?

My DVD says "Licensed for use only by students and faculty" around the edge of the disc. In the middle it says "Windows 7 Professional - 64-bit x64 Upgrade - October 2009 Student Systems Media"

Any information would be greatly appreciated. Thank you.

The Windows 7 key should work with both 32 and 64 bit, but only one can be installed at a time per license key.

You may need to call to reactivate. If you have trouble activating Windows 7 open the Windows Activation Wizard while in Windows 7 to use the phone and activate Windows:
If you are currently in the install process - at the Enter Your Product Key page, do not enter your key and uncheck "Automatically Activate When Online"
1. When you reach the desktop, Click Start, then in the Search box type:  slui.exe 4
2. Press Enter on your Keyboard
3. Select your Country.
4. Select the Phone Activation option, then call the number given and hold for a real person.
