erwin DM License Administrator, how to set the vendor daemon port to a fixed port

The Vendor daemon port is picked at random by the license administrator software when it starts.  That is hit or miss so it is good to set that to a known open port on the host machine, the company network, and the machine where erwin dm is being run.  To do that,

Launch the erwin License Server Administrator
go to Administration and log in
Click vendor daemon configuration
Click administer
Choose use this port and type the number of a known open port on the host machine, the company network, and the machine where erwin dm is being run.

Press save
Restart the service
