In this example, the params (ie Property values) are Added (Add Row) to the MSI and then saved. Once you do this, you'll see from the install log they're not configured. 

This allows you to put into GPO. * GPO you cannot specify params.

Property(S): WSSERVER = VS8CPN
Property(S): WSDRIVE = C:\
Property(S): INSTALLDRIVE = C:\qs
Property(S): WSPORT = 9001
