Abstract: When the application (P) is activated (enabled, validated) by the second activation key (K2) issued by the first electronic apparatus (10), the control circuit (21) of the second electronic apparatus (20) stores the application identifier (PI), i.e., information for specifying the application (P) in the backup area (the second storage area (282)). Even if the application (P) is accidentally deleted from the second electronic apparatus (20), the application (P) can be recovered by identifying the application based on the information in the backup area.

Abstract: An electronic apparatus includes: an input module configured to input an export instruction and an electronic apparatus identifier, the export instruction instructing to export an application, the electronic apparatus identifier corresponding to one different electronic apparatus; a controller module configured to generate an activation key on a basis of the electronic apparatus identifier where the export instruction is input, the activation key being for activating the application only in the one different electronic apparatus, control to output a package file including the application and the activation key, and inactivate the application after a certain replacement transition time period passes, the certain replacement transition time period starting from an output time point of the package file; and an output module configured to output the package file controlled by the controller module.

Abstract: A storage device stores, for each of one or more function expansion applications, the hardware component necessary for operation of the function expansion application. A control circuit is configured to detect that there is a failure in any of the plurality of hardware components, determine whether or not there is the function expansion application that needs, for operation thereof, the hardware component from which a failure has been detected, and perform control so that an operation mode is switched to a first degeneracy mode in which the detected hardware component is not used where there is no function expansion application that needs the detected hardware component, and the other hardware components are used.

Abstract: An apparatus setup system includes: a first electronic apparatus; and a second electronic apparatus, the first electronic apparatus including a first controller module configured to generate a package file where an export instruction is input, the export instruction instructing to export an application, the package file at least including the application identifier and an electronic apparatus identifier of one different electronic apparatus, the second electronic apparatus including a second controller module configured to where the package file is input, check the electronic apparatus identifier included in the input package file against the electronic apparatus identifier stored in the second storage device, and where it is determined that the electronic apparatus identifier included in the input package file matches the electronic apparatus identifier stored in the second storage device, activate the application identified by the application identifier included in the package file.

Abstract: An information processing system includes: one or more information processing apparatuses; and a management server, in which the management server includes a license key table management unit that receives inputs of a serial number, an application ID, and a license key from an administrator and registers them in a license key table, and a license key authentication unit that extracts the corresponding license key from the license key table by using the application ID and the serial number received from the information processing apparatus in which the application program is installed, and performs license key authentication of the application program by using the extracted license key, and the one or more information processing apparatuses each include an application installation unit that installs the application program, and an authentication requesting unit that transmits the application ID and the serial number to the management server to request for license key authentication.
