Re: Installing Vista 64 after installing Vista 32
As mentioned you have to do a clean custom install of the 64-bit version.
You can use Windows Easy Transfer (if it works for you) to transfer your
data and settings. You will have to reinstall all your programs. If you
don't have a need for 64-bit, I suggest you stick with 32-bit. If you do
convert, make sure FIRST that you have 64-bit drivers available for ALL your
hardware, internal and external and that all your programs are going to run
on the 64-bit platform or realise you may have to replace hardware and
software. The same license will work with BOTH versions, though only one at
a time and you will have to use telephone install as the license will be 'in
use' . Good luck.
