Note

Only PUBLIC PROPERTIES can be modified using the command line. All property names on the command line are interpreted as uppercase but the value retains case sensitivity. If you enter MyProperty at a command line, the installer overrides the value of MYPROPERTY and not the value of MyProperty in the Property table.
