You can only use the product key for one Vista installation.
If you wish to install a second installation, then you'll need
to purchase a second product key (license).
In other words, you can install either the 32-bit or 64-bit version
of Vista using the product key, but you cannot install and activate
the other version using the same product key unless you remove
the first version.

Hello Folks! This is my 1st post on these boards... I have a brand new
computer that has 2 x 500GB Hard Drives. I also have the 2 DVD 32 bit
(x86) & 64 bit (x64) Vista Ultimate Retail pack that has 1 validation
code. I would like to put the 64bit operating system on 1st Hard Drive
and the 32bit on the 2nd Hard Drive. Would anybody out there know if
when it comes to validating the software if the serial numbers of the
Hard Drives will affect the process since all the other components are
the same in the one box. Thanks D.
