chances are its actually a cd image. i suggest getting Daemon Tools. It makes a virtual drive for you to mount the image in. Then you should be able to watch it in anything that plays vcds or whatever type it is.

if it asks you to install the bar etc during the installation, don't. i can't remember if mine had that crap in it.
