Abstract
When upgrading a software installed in an analysis device PC (1) that is not connected to the Internet (4), a user performs a predetermined operation with the analysis device PC (1) to acquire a license authentication cancellation key. When the user accesses a server (5) from a user terminal (2) with a predetermined account and enters the license authentication cancellation key, a license authentication cancellation unit (52) cancels authentication of a license for a previous version. Furthermore, when the user enters a product serial number of an upgrade version software 3 and the like, an upgrade verification unit (53) confirms that the user owns the license for the previous version and that the authentication has been canceled, and an activation key issue unit (54) issues an activation key for an upgrade license. Using this, a device user activates the upgraded software installed in the analysis device PC (1). In this way, when upgrading the software on the offline PC, license authentication can be simply performed.
