I'm running Windows Vista ultimate. Daemon-Tools works very well on it. Simply go to the download page and install it
http://www.daemon-tools.cc/dtcc/download.php If you're running the 64 bit version of Windows Vista, install the 64 bit version of Daemon-Tools. If you're running the 32 bit version of Windows vista, install the 32 bit version of daemon-tools. If you have any problems, either myself or another member of the community will be glad to help you. You can find out what version of Vista you are running, by clicking the Start button, right clicking computer, then choosing properties from the menu. It will tell you whether your running the 64 bit or 32 version of vista.
