InstallShield 12 » InstallScript Language Reference
System variables are predefined script 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 installation process begins, and it is not necessary to declare these variables in your script.
NOTE
Many Windows Installer directory properties—such as INSTALLDIR, AppDataFolder, and TempFolder—are available directly as variables in your script.
Some of the system variables have corresponding text substitutions. The installation internally uses text substitution to set the values of certain system variables as shown in the following tables. You can use these text substitutions in your script in the same way that you use text substitutions that you have defined.
