Hello LGC, and welcome to Eight Forums,
Yes, you can replace the 32-bit Vista with a 64-bit Windows 8 upgrade.
If you like, you could also use the Windows 8 Upgrade Assistant to purchase and download the £24.99 ($39.99) Windows 8 upgrade ISO file on your 64-bit W7, create a bootable DVD or USB with the ISO, then clean install the 64-bit Windows 8 upgrade on your 32-bit Vista computer. During installation, you would enter the W8 product key.
Hope this helps,
The Windows 8 Upgrade Assistant only verifies that the computer you run it on qualifies for the upgrade. It doesn't tie that computer to the Windows 8 upgrade since it's only a check. You can download and purchase from any computer your like, but since you want a 64-bit copy of Windows 8 upgrade, you will only be able to do so from a 64-bit Windows.
Yes, you will get a new Windows 8 product key when you purchase the Windows 8 upgrade. This would be the key you enter during installation. The key is good for either 32-bit or 64-bit Windows 8.
You will not be able to upgrade from 32-bit to 64-bit. Instead, you must do a clean install with the Windows 8 upgrade copy.
You must be sick of explaining this, but I'll ask one more time. I also have a 32-bit Vista and want to clean install 64-bit Windows 8 over it.
I have a valid W7 64-bit that qualifies for the £14.99 upgrade. Can I download this ISO from this laptop and install over the Vista drive - without losing the right to use the W7 OS - this is the important bit for me.
Also, in the future can I transfer the W8 OS to another harddrive when I build my new PC??
