A communication setup program eliminates the need for setting communication data common to multiple applications individually for each application. The communication setup program configures communication data that is reflected by the applications when each application is loaded, and provides a device selection module for selecting a target communication device from among one or more devices setup on the computer; a related application extraction module for extracting related applications that support the selected device from among a plurality of applications installed on the computer; a communication data setup module for configuring the communication data used by related applications to communicate with the selected device; and a communication data ID output module for providing a communication data ID for referencing the configured communication data to the extracted applications.
