The software works on XP and W7. You just have to intall it directly on C drive versus C drive\Programs folder in Vista or W7 (this means you need to hit the backspace button to clear the word programs in the default install location. If you can turn your computer on, you have all the needed know how).
The video-out will be dependent on your computer set up. For a projector connect to your monitor output. If you have an HDMI out on your computer then you can use an HDMI cable to a flat screen TV. In reality this is a computer - projector/monitor issue that is independent of the trainer.
