A PC determines whether or not firmware (a first firmware), which has already been downloaded to an image forming apparatus, is present, and, when the first firmware is present on the image forming apparatus, acquires information about the first firmware and information about a second firmware that matches the image forming apparatus. When the application of second firmware to the image forming apparatus is selected, the PC acquires a difference package corresponding to the difference between first firmware and second firmware based on information about first and second firmware, and applies a difference package and first firmware to the image forming apparatus.
