OK, first of all, you need to create a **plain **text file in the root of your CD with the filename “AUTORUN.INF”.
Next, enter the following code in AUTORUN.INF:
[autorun]
open="Start.exe"
icon="Icon.ico"
Where “Start.exe” is the name of the program you want to run and “Icon.ico” is the filename of the icon you want to appear for the CD in My Computer. The icon=“Icon.ico” line is optional by the way.
If you’ve tried this and it doesn’t work then the most likely reason is probably that the user has turned off AutoRun in their system settings. There’s really nothing you can do about this other than give them instructions on what to click on if it doesn’t start automatically.
