1:LaunchApp (szCommand, szCmdLine);
The LaunchApp function allows you to launch another application
program from within the script. The launched application and the
script run simultaneously. InstallShield has no control over the
launched application and cannot determine if the launched application
runs successfully. Launched applications run like any other
application you may start while running InstallShield. You can launch
any application from InstallShield that you can normally launch from
the operating system
2:LaunchAppAndWait (szProgram, szCmdLine, lWait);
