Select Yes to have InstallShield create an Autorun.inf file for you during the build. When placed on the root of a CD-ROM or other removable media, Autorun.inf causes your setup to launch as soon as the media is recognized by the operating system. If you choose to create Setup.exe as part of your installation, the autorun file points to the executable. If you disable the Setup.exe option, the autorun file points to your .msi file.
