I downloaded Vista Ultimate SP2 x64 iso from TechNet and used the Windows 7 USB/DVD Tool to successfully place the files from the iso onto a USB Flash Drive. I have no spare drive to actually install Vista on,nor do I want to. I also used the Windows 7 USB/DVD Tool for a 64bit Office 2010 Beta2 transfer from the WZOR torrent iso to a USB Flash Drive. The full Office 2010 Beta2 x64 installation took all of about 4 minutes from the USB Flash Drive.
