Below are some key concepts regarding your PROKON license:
License key: A special file that contain your license information. Your license key is supplied either on your DVD-ROM or made available via electronic download.
Expiry date: Annual rental license have a fixed expiry date 12 months after order. Purchased licences allow perpetual use of the programs, but software maintenance (program updates and technical support) expires after 12 months. Both annual rental and software maintenance of purchased programs can be renewed.
Sets: The modules that you order is grouped in a set. Your license can include up to two sets. Here is an example: You have a group of engineers that specialise in steel design, and another group that specialises in concrete design. Both groups use the Sumo Structural Modeller module to calculate forces in building frames. Your PROKON license can be configured with two sets. Set 1(Steel) will contain Sumo Structural Modeller module and some steel member and connection design modules. Set 2 (Concrete) will also contain the Sumo Structural Modeller module and some concrete design modules. The two sets form part of the same license key, and can be activated and used separately. When combining two sets in the same license key, a substantial discount is applicable to modules that are included in both sets.
Workstations: A workstation is one set of programs that is accessible on a standalone computer or network. Each set of modules in your license key has a number of workstations assigned to it. The number of workstations determine the number of times the set of programs can be used simultaneous. Simultaneous use can either be standalone computers that have been activated individually, or users accessing PROKON on a network at the same time. Expanding on the example above, imagine that Set 1 (Steel) has three workstations and Set 2 (Concrete) two. The license key therefore allows five users to access PROKON at the same time: three using the steel design modules, and two using the concrete design modules. All five users will be able to access Sumo Structural Modeller that is included in both sets.
Activation: You have to activate your programs in order to access their full capacity. When you activate your programs, you can choose the number of workstations for Set 1 and Set 2 to activate. The number of available (for activation) workstations is decremented accordingly. In the above example, Set 1 can be activated on three standalone computers, or on a network for simultaneous use by three engineers.
Deactivation: You can deactivate an active set of programs at any time. The number of available workstations is incremented accordingly.
Note: The Prokon License Server (an Internet service) keeps track of the number of workstations that have been activated and the number of workstations available for activation. An Internet connection is required to activate or deactivate your programs. An Internet connection is however not required to use PROKON once it has been activated.
