MODE

InstallShield 2019 » InstallScript Language Reference

The system variable MODE holds one of the following constant values (note that the value cannot be changed at run time):

MODE
Constant	Meaning
SILENTMODE	Indicates that Setup.exe is running in silent mode. (That is, the user ran Setup.exe with the /s argument.)
NORMALMODE	Indicates Setup.exe is running in normal mode.
RECORDMODE	Indicates Setup.exe is automatically generating a silent setup file (.iss file), which is a record of the setup input, by default in the Windows folder. (That is, when you run Setup.exe with the /r argument.)

You can use the system variable MODE in if statements to control the flow of your script based on mode, as shown below:

if (MODE = SILENTMODE) then

// Perform silent setup actions and events.

else

// Perform normal setup actions and events.

endif;

Note • For a Basic MSI project, you can find if the user is running the installation in silent mode with the Windows Installer condition “UILevel=2”.
