32bit Windows key on 64bit install

[tuberolector]

I am preparing to do a new system, and I need to buy a new Windows license for this build. 

 

After looking on Amazon for a copy of Windows 7 (I much prefer it over Windows 8), I found a 32-bit copy that costs about $85 (here), and for a 64-bit version, it costs about $100 (here). 

 

I have another copy of Windows 7 Home Premium that has both 64-bit and 32-bit disks, so could I use the key that comes with the 32-bit only copy (above) with the 64-bit disk that I already have? 

 

I know that it won't work unless they are the same version, but doesn't that just mean Home Premium vs Professional? 

 

Thanks for your help.

It will not work. The keys are interchangeable only OEM settings. In consumer settings the key is already linked to a specific version of windows.

should work fine, Windows 7 home premium is the license.  64Bit is just the architecture so, but its still the same product. 

 

JUST make sure if its an OEM key, that you only use 32bit or 64bit.  OEM copies are designed for only one disk I think, so if you have windows 7 OEM 32bit, its only able to be on a 32bit version.

No it won't work, you can't use 32 bit key on it. Plus your windows 7 disk has one key that can be used once on 32 bit and once in 64 bit but i'm not sure about this because i haven't tried this before.

It won't work. You can use 64bit key with 32bit install but not otherway around.
