Hi Julie
Unfortunately it would seem you have hit one of the other issues I alluded to initially when I admonished it was "iffy". 
IT staff often disable autorun and more and more operating systems are just having it turned off because it's a huge security risk. Sorry, but those are the breaks.
Likely the next best thing you can do is to structure the CD... Hmmm, in typing the term "CD" it occurs to ask this. This *IS* a standard CD-ROM, right? Because it only works for CDs (when it works). DVDs have a totally different structure and if you used DVD it won't work. But I digress.
Anyhoo, your likely next best move is a ReadMe.TXT file or something that provides simple instructions to the user on opening the file browser and what file to double-click to launch things.
Cheers... Rick
