Using Flexera License Manager (FlexLM) for multiple vendors

Quick little video (less than 5min) showing how you can use the network licensing scheme not just for Autodesk, but also for Solidworks, SmartBIM, ArcGIS, and many other software vendors. I will explain how you can consolidate your license servers by running multiple license server services, each server it’s own vendor without having multiple actual servers, physical or virtual. This is useful since everyone wants to maximize every server on their networks and also cut down the number of servers to a minimum.
