• and
• c-2) in a case where it is determined that the one service cannot be provided even by using any of the plurality of applications, transmitting the providing request of the one service to an external server that is another service providing device different from the service providing device and arranged outside the LAN, so as to cause the external server to start the service processing corresponding to the providing request to provide the client with the one service, and downloading a specific application for providing the one service from the external server or another external device to install the specific application in the service providing device, after the installation of the specific application to the service providing device is completed, taking over, from the external server, the service processing that has been started by the external server resulting from the transmission of the providing request of the one service, and then executing the service processing to provide the client with the one service.
