If you are sure you have a correct server configuration and a valid license, then this problem may arise in the following cases :

1. Your Network port is already used by another application. In this case, you just have to choose another value.

2. Another server is already running on this computer (multi-user computing, for example). In this case, you must find another computer and make it your license server host from which you will launch your computation.
