The ArcGIS license manager does not control ESRI licenses via a license file, but through trusted storage.
This means that the ArcGIS license file may contain definitions of the license server, port numbers and Server addresses, but not licensed features such as Viewer, GeoStats, Publisher and Schematics.
When the OpenLM server is configured to read the license file, it expects the licenses to show in that file. Otherwise – these licenses will not be presented.
So, in order to present license usage for ESRI licenses, please make sure the “Read license file” check box remains clear. See image below.
