Communicator software is a tool used for many applications but should only be downloaded if directed by an Ultimate Software staff member. The Communicator Programming Language (CPL) uses the Communicator as a base program for developers. Almost all applications will need a separate license and application file supplied by Ultimate. These files are primarily used as a part of an application like Smoke Signal, OnTimeforAnything, Doctor Reminder Software, Ultimate Communicator with Smart Plug-in’s, or any custom software program developed for our customers and dealers. This may require a new activation and license fee.
