Issue
The pop-up window with the error "Error Adding Device: The number of Device Licenses is insufficient" is displayed after attempting to add a new device into PME Management Console. This occurs after the details are entered into the Configuration window and pressing "OK." The device consequently does not appear in the device table.
The full error:
"The number of Device Licenses is insufficient
Entry-Range Device Licenses: 0
Mid-Range Device Licenses: 0
High-End Device Licenses: 0

Causes
The PME licensing platform is dependent on the web applications server. When the server is not functional, the licensing platform loses access to information about the licenses on the system.
Cause #1
The PME installer enables and configures the Internet Information Services (IIS) to host the different Web Applications. The "Applications Modules App Pool" should be running automatically to host the web application.
Cause #2
Power Monitoring Expert leverages several ION services. The ION Application Modules Provider Engine Host hosts web services that provide data processing for the Web Applications component. It should be started for the Web apps to be functional. For a full list of PME Windows services, please view the official PME user guide https://digital-energy-help.se.com/pme/content/8_reference/planning/ref_pmewindowsservices.htm?Highlight=pme windows services.
