This version is perfect for simulating small systems, and for use as a demonstration tool. It is fully featured and limited only by network size and a few other non-essential features. The free edition utilizes our newly developed, centralized licensing manager — a cloud-based solution, which licenses the application through certificates. By design, a certificate allows the user to run the software without being continuously online. Each certificate is recharged with a new cycle whenever the client contacts the server. This new licensing system greatly simplifies the deployment, maintenance, and use of the software.
