Licensing terms


CAE Fidesys can be purchased both for a limited period (starting from 1 year) and for an unlimited period.

Types of keys

The key allows you to use CAE Fidesys in accordance with the terms of a specific license. The key can be either software or hardware (USB). The software key is tied to a specific computer and cannot be used on another computer, if it is not a network key (see the next section); the hardware key can be moved from one computer to another.

Network keys

The software key can also be a network key. In this case, the computer, where this key is installed, will be the license server and will allow CAE Fidesys to run on other computers on the network without activation. This option is recommended if you need to install a large number of copies within a local network.
