If you are distributing an application developed using DP4 to a new user, you also need to include the DP4 licence file, the DP4 system database, and the standard DP4 runtime programs:
The runtime programs include the database manager, the user interface manager, the DP4 setup and database backup utilities. Depending on the configuration of the user system, you may include the DP4 network runtime programs, and any special device drivers required for the user system.
