InstallShield 11 » InstallScript Language Reference
System variables are predefined variables that contain information such as the source path, the target path, the Windows folder, and the Windows system folder. InstallShield automatically initializes these system variables when the setup process begins, and it is not necessary to declare these variables in your script.
Many Windows Installer directory properties—such as INSTALLDIR, AppDataFolder, and TempFolder—are available directly as variables in your script.
The following list describes all of the InstallScript system variables:
