Abstract: An image forming apparatus installs a license instructed to be installed when a reliable date has been successfully acquired from a server. When the reliable date fails to be acquired and the license instructed to be installed is a valid-days-designated license, the information forming apparatus installs the valid-days-designated license based on the image forming apparatus' built-in clock. When the reliable date fails to be acquired and the license instructed to be installed is an expiration-date-designated license, the information forming apparatus does not install the expiration-date-designated license.

Abstract: The information processing apparatus obtains attribute information of an application from the server in accordance with an instruction for instructing an update of an application stored in the storage unit and searches for and retrieves an application in a dependency relationship with the application to be updated based on the attribute information.
