OK, you could try a couple of things. First, got to my computer, right click on the cd drive and see if there is a menu option called "autoplay". If there is click on it.

You could also right click on the setup.exe program and select open or run.

You might also see if there is a program called "installer".

When I put my disk in the CD drive it automatically loads up the menu, so mine is behaving differently than yours. Maybe someone else has had the problem and will respond if they found a fix.
