InstallShield setup file in self-extracting Zip files for Software Installation

InstallShield changed the way that setup.exe launched the _isdel routine, so that it became transparent to the self-extractor. Installshield seems to have addressed the issue with the /SMS switch.

The change made it so that the self-extractor does not see the ISDEL program being launched, due to the way that the setup program itself spawns the process. However, we've heard from a few users who have overcome the problem by including the /SMS switch with the command to issue.

Example:

  .\setup.exe /SMS

Note: /SMS must be specified in uppercase
