We publish our products in two ways. With commercial and free licensing.
The free license allows to test our products, and also to use them without restrictions, however, for the installations made without commercial license, the support of our center of competence or a partner network can't be provided.
Free and commercial products based on the same code. So you can acquire the commercial license after free version installation.
