I recently bought a new computer with the 64-bit edition of Vista Home Premium installed.

I downloaded the free Microsoft Virtual PC 2007 and tried to install it. I was informed that I need the 64-bit version. Can you tell me where I can obtain this, as I would like to install Windows XP on the new computer, using a virtual machine.

You need to use the correct version of Virtual PC to match the version of Windows your computer has installed. For most of us, who are using 32-bit versions of Windows XP and Windows Vista, it’s not a problem. For the rest, you will need the 64-bit edition of Virtual PC. Both versions of Virtual PC can be downloaded.
