Hello, Yes and No, Yes, you can use the 64bit disk to install. No, it will not be an upgrade. Changing from 32bit to 64bit requires a clean install of Windows. You will need to install all programs and such from scratch.
Hello, I am the owner of both a XPS 730 desktop and a Studio XPS 1640 laptop. I was recently thinking about upgrading my desktop from the 32-bit OS which it came with to a 64-bit OS. Now, my laptop came with a 64-bit Vista reinstallation disc. Is it possible for me to use that disc to upgrade my desktop?   Thank you for your help.
