One server can host multiple Flex-based license managers, but a port conflict may occur when more than one license manager is present. Each license manager should automatically use the first available port number between 27000 and 27009. However, a license manager occasionally will try to use port 27000, even when it is already in use.
This issue may present itself when installing the Minitab License Manager for the first time or when replacing your renewed license file on the server. While Flexnet error −97 is the most common error reported for this situation, other Flexnet error numbers can also appear.

If you specified a different port number during installation, you need to either redeploy the software or provide the end user with the new port number. The software will prompt for the port number and license server name if the information does not match.
If a firewall is turned on, you must allow access on the port specified in the license file.
