Abstract: An application installing method according to the present invention in which an application file includes at least two application encrypting data in which the executable files are respectively encrypted using different encryption algorithms, and a license file includes at least two license encryption data in which application decryption keys for decrypting the application encryption data are encrypted using respectively different encryption algorithms. The process execution apparatus includes a calculation unit configured to execute the executable file, and a storage unit configured to store the application file and the license file. The method includes a step of decrypting the application encryption data by use of the application decryption key with the calculation unit based on the level of priority of the predesignated application encryption data stored in the storage unit, and installing the executable file corresponding to the application encryption data.

Abstract: A device management module acquires the configuration information from the image forming apparatus and acquires product information of a product that corresponds to the image forming apparatus. The device management module determines whether the condition for validating the application that corresponds to the above-described product in the image forming apparatus is satisfied based on the acquired configuration information and the acquired product information. If the condition is satisfied, the device management module transmits license issuance request information to the image forming apparatus. The image forming apparatus transmits a license issuance request to the device management module to acquire a license and validates the application based on the acquired license.

Abstract: A plurality of licenses included in a package license and respectively corresponding to a plurality of applications is stored in a first storage unit, the plurality of applications is stored in a second storage unit, and a product information table associating product information with application information for identifying each of the applications is stored in the second storage unit.

Abstract: An image processing apparatus that enables to start an application that is required to start by stopping an application that is not used by a user to reserve an available memory capacity when receiving a startup request. A first determination unit determines a memory usage of the application that receives the startup instruction. A second determination unit determines an available memory capacity. A third determination unit determines an application that is not used by a user. A stopping unit stops the application determined by the third determination unit among the executing applications when the memory usage determined by the first determination unit is more than the available memory capacity determined by the second determination unit. A starting unit starts the application that receives the startup instruction using the available memory capacity that increases because the stopping unit stops the determined application.

Abstract: An information distributing apparatus obtains a serial number input from the image forming apparatus and information regarding an apparatus connected to the image forming apparatus. The information distributing apparatus determines permission or inhibition of distribution with respect to each program specified by the serial number.

Abstract: A distribution apparatus manages a distribution history of a program and, when a request about a program applicable to a device including device identification information and a version of the program of the device is received from the device, if an update result indicates successful updating in the distribution history about the program, transmits information indicating a post-update version included in the distribution history to the device as a response to the request.

Abstract: An image processing apparatus that enables to start an application that is required to start by stopping an application that is not used by a user to reserve an available memory capacity when receiving a startup request. A first determination unit determines a memory usage of the application that receives the startup instruction. A second determination unit determines an available memory capacity. A third determination unit determines an application that is not used by a user. A stopping unit stops the application determined by the third determination unit among the executing applications when the memory usage determined by the first determination unit is more than the available memory capacity determined by the second determination unit. A starting unit starts the application that receives the startup instruction using the available memory capacity that increases because the stopping unit stops the determined application.
