6. A computer program product comprising a computer usable medium having computer-readable program codes embodied in the medium to be executed by a computer that includes a storage unit that stores therein a license file containing an expiration date of a license of an application and a class of the license, the program codes when executed causing the computer to execute:
acquiring the expiration date from the license file;
determining whether the expiration date acquired at the acquiring has passed;
identifying a class of the license whose expiration date is detected as having passed at the determining, based or the license file;
determining a method of performing an update process based on the class identified at the identifying;
acquiring a license file from the license management server based on the method of performing the update process determines at the determining; and
replacing the license file stored in the storage unit with the license file acquired at the acquiring the license file.
