You are looking to perform a silent / unattended install of the Defender Administration Console or want to run the installer without certain options, for example, you don't want to create the Defender OU as it already exists in Active Directory (AD).
The following swtiches are supported:
/SILENT Silent Installation
The Silent installation will update the Schema (if required), create the 'Defender' OU and install the GUI by default, however, it only attempts to create the 'Defender' OU if it does not already exist.
/NODLG No dialog - not silent mode, still has progress dialog and message boxes
/PATH:xxxxx Specify a specific installation location (the current installed location will override this setting.)
/NOLOG Do not write to the installation log
/SCHEMA Install the Schema extensions
/NOSCHEMA Do not install the Schema extensions
/NOORGUNIT Do not create the 'Defender' Organizational Unit
The 'Create Defender OU' option is off by default in the latest build when installing without switches.
/NOGUI Do not install the GUI
/CAR Install Defender Control Access Rights
/NOVER Overwrite existing files
Note that Defender 5.7 adds the flag:
/NOTRIAL Do not install the trial licenses.
