The STK Help has an entire section dedicated to the different ways to acquire licenses for STK and the different license types AGI provides. You can learn more about licensing STK at STK Help > Licensing > Overview.
There are four (4) types of licenses available for the STK software suite: node locked, named user, network token (NT), and dongle.
The four license types each have different modes of operations:
-
Node-locked licenses are each assigned to a dedicated computer.
-
Named-user licenses are associated with a single individual user and may be installed on multiple workstations/networks. Users are limited to three (3) individual workstations on up to three (3) different networks.
-
Network (NT) licenses reside on a server, and like borrowing library books, users "check out" available licenses as needed. Any user on the same network may have access to these licenses.
-
Dongle licenses are tied to the unique serial number of an associated hardware dongle. The dongle may be moved among multiple workstations as long as the associated licenses are also present.
Which type of license is right for me?
Different licenses work best for different users in various settings and are offered to help you maximize your software investment.
-
Node-locked licenses are best suited for operational settings where multiple users will run STK on the same computer but never at the same time. As one shift goes off console and a new one comes on, the same licenses will suffice without any denial of access.
-
Named-user licenses provide for portability across locations and networks. A named-user license will allow the designated user to have access to STK on multiple workstations on the same network as long as that person uses a consistent login ID. AGI will provide licenses for up to three (3) unique login IDs. This is especially convenient for users who move between different closed networks with varying levels of security.
-
Network (NT) licenses can be shared across a network. There is no loss of performance with this type of license arrangement, but users may only check out licenses that are not otherwise in use. For example, imagine a small company with two STK PRO licenses and one STK Comm license. If two users are working on STK, both can use STK PRO, but only one would have access to STK Comm. Or, three users could work on STK, two running STK PRO only and the third running STK Comm.
-
Dongle licenses are the best option when it's necessary to move licenses from one workstation to another on a regular basis. This is particularly useful if moving between multiple disconnected networks where a network license won't suffice.
