how can i change win 7 from 64 bit to 32 bit? it seems that everything is set up for 32 bit and drivers etc are easier to find and I don't have nearly as many lockups or errors with 32 bit
You would need to totally reinstall (you may need to BUY another key as well)....but 64 bit will run almost all 32 bit programs anyway, so your problem is likely to be elsewhere....software or hardware, buy not windows...
if your version of Windows 7 cam with both discs in the case the key should work for either. But I think you have other issues as Windows 7 will run both 32 & 64 bit software at the same time with no issues.
I would check you have the right drivers for the motherboard first
