If you are trying to install a regular RobotWare option for ProfiBus, then that option must exist in your robot license keystring and must be selected in the system configurator of RobInstall when you build a new system. You cannot just install new system software after a system is built, you must build and install a new system to add new options, and you cannot install options that are not included in your keystring. If you need to have an option added to a keystring, you must contact your local ABB support organization to purchase the option. They will then provide you with an updated license keystring that you can use to build a new system with the option you desire.
