As I said, you have to write an autorun.inf file and place it in the root directory.
If you google "how to create autorun.inf" you'll get all the information you want.
The text file will be very similar to these two lines
[autorun]
open = FolderWhereDVD@accessIs/NameOfInstaller.exe
Not much more than that!
