INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSOR, PORTABLE TERMINAL, INSTALLATION TARGET SETTING METHOD AND PROGRAM

PROBLEM TO BE SOLVED: To enable an installation target device to be easily selected and installed on an information processor side even when the device has only a display device with low display capability.SOLUTION: A PC 5 acquires device information necessary for the installation of a device driver via a radio LAN from each of a plurality of devices 1, 2 and 3, and displays the device information in a form of list at a display part 26. When a user holds a mobile terminal 7 on his or her desired device to be installed in the PC 5, the mobile terminal acquires the device information of the device by NFC communication from the device. The mobile terminal 7 transmits the acquired device information via the radio LAN to the PC 5. When there exists any device information which is coincident with the device information transmitted from the mobile terminal 7 among device information preliminarily acquired and displayed in a form of list by the PC 5, the PC 5 sets the device corresponding to the device information as an installation target, and advances the installation of the device.
