I'm trying to auto install lotus notus. I use this command: msiexec -i C:\6.5.5\6.5.5.msi USERNAME="***" COMPANYNAME="***" Everything works but i have to specify a few other fields, But how can i know with property name the field has... USERNAME and COMPANYNAME were easy to guess... Is there a way to get the info of all property's that the installer uses?
