Put the boot in

I've had all the stuff come through for my Internet course from ICS. How to build web pages. Actually, it came last week but I wanted to get all the decorating over and done with before starting it. Well, the decorators are still here but I'm no longe required so I thought I'd insert the disc and install the software. No go. The disc should autorun but for some reason it isn't. I tried going to the START menu, selecting RUN and typing 'd:\setup.exe' but that didn't work. I've explored the CD. but there doesn't seem to be any actual setup program on it. So, what do I do now? It seems a bit sad, not being able to do a course cos I'm unable to even intsall the software!
