FlexNET "Error -89: This platform not authorized by license." - ID 2004

Why do I receive the following error message?
"FlexNET Error -89: This platform not authorized by license."

This error is commonly seen when multiple vendor daemons (other FlexNET license managers) are run on the same server, creating a network port conflict. To resolve this conflict, you can set the Minitab License Manager to run on another port such as 27005.
