If you want the Tuner to use a License Server located on a different machine, edit the license_client.conf file in the bin directory in the Tuner installation directory.
This file consists of two variables:
ip_address is the IP address of the License Server you wish to use. By default, this is set to the local IP address of 127.0.0.1
port_number is the port number to use when making license requests. By default, this is set to 7569.
