Running XP Pro and bought Vista Ultimate. I have setup XP, 32bit & 64bit
vista on 3 seperate partitions. I would like to see if I can get all my
Hardware working in 64bit, and see what the benifets are vs 32bit version.
(Intel 6600 w/4GB Ram)

I installed and configured 64bit first and have activiated the product using
the Key on the package. When I booted into 32bit and tried to activate it,
I get "The product key you typed is already in use".

I am pretty sure I will stick with 32bit, but was hoping to see over time if
64bit was what I wanted to use, and if all the drivers work. Can I not
active both my Vista copies? If I need to remove 1 copy, then, can I remove
the 64bit partition and just stick with XP and Vista 32 bit, or will trying
to remove it cause boot up issues?

Any links or pointers to how to do this would be great.
