Vista 64bit from 32bit install question

Hi @ll

I have 2 PCs and 2 retail versions of Vista Home Premium.

My first comp is allready upgraded to 64bit when I built it 2 years ago
when Vista was launched (I installed the 32 bit ordered the DVD for
64bit and reinstalled)

Now I just built a second computer and installed a second retail Vista
Home Premium SP1 32bit. I would like to upgrade this one to 64 bit as
well.

My question is, can I use the 64bit DVD I had to mail order couple
years ago and link it to my second 32bit product key or do I need to
mail order a second 64bit DVD?

I am asking because I am not sure that if I use the same CD, I will
defacto cancel the 64bit install on my original computer when I install
it on the second one, in which case I have no alternative but ask for
another 64bit disc and wait several weeks for them to send me the disc.

Cheers

since it is going to ask you for serial number, you're about to find out...

It is the product key, not the disk, which determines the version of
Vista installed and is used for activation. All 32-bit and 64-bit disks
are the same, whatever labels they carry, so there are only 4 Vista
installation disks - 32 and 64 bit RTM, and 32 and 64 bit SP1.

You can safely use the 64-bit disk you have with your second product key.

Any Vista installation disk can be used, without a product key, to
install a 30-day trial of any version of Vista. 32-bit disks can only
install 32-bit Vista and 64-bit disks only 64-bit Vista.
