Abstract

A server transmits, to clients, display data for displaying a plurality of input areas for pieces of identification information which identify apparatuses in which software is to be installed. The server receives the plurality of pieces of identification information input to the input areas. The server then issues, to the clients, license information for permitting installation of the software to the apparatuses corresponding to the pieces of received identification information. This makes it possible to efficiently issue license information of software.
