Floating / network licenses

License server

When dealing with a floating/network license, don't load the license file into the configuration editor. The following steps describe how to easily install a license server on Windows using the LM-X End-user Tools (Windows only).

  1. Download and run "lmx-enduser-tools_win32_x86.msi".

  2. During the installation process, make sure that "Install LM-X server" is checked.

    Browse to find our "liblmxvendor.dll" in the MiddleVR installation path /bin/licensing

    Keep "Install LM-X license server as a service" checked.

After the installation, open the configuration file "lmx-serv.cfg" from the LM-X tool installation folder (for example "C:\Program Files (x86)\X-Formation\LM-X End-user Tools 4.5.4\lmx-serv.cfg").

Set the value LICENSE_FILE to the path leading to your floating/network license file.

You can choose your TCP_LISTEN_PORT if needed.

Make sure to open this port (TCP and UDP) in your firewall, both on the license server machine and the client machines.

If there are any problems running the license server, the log file will indicate the cause of the problem. You can find the log file at the path indicated in the configuration file value LOG_FILE. If still not found, check to make sure that the path is correct.

You also can manage the license server through a web GUI:

Open a web browser to the right machine IP address and the right license server port, for example: "http://localhost:6200/".

The administrator password is the one defined in the license server configuration file at REMOTE_ACCESS_PASSWORD.

Configuring clients

On the client machines, you can either:

  • use the License configuration tool lmxconfigtool.exe from the MiddleVR folder in the Start menu:

    In the Client Application License Path tab, specify the network license server in the form of : 6200@192.168.1.1. You can also use a network name instead of an IP address.

  • or, set the LMX_LICENSE_PATH environment variable to the network license server, in the same form.

Storing your license in a different folder

You can store your license in a different folder and set the LMX_LICENSE_PATH environment variable to the full path of the license.
