NTA Could not load file or assembly Solarwinds.Licensing.Framework

Updated December 21, 2016


When upgrading NTA, the following error is found in the logs after it has been installed:

ERROR SolarWinds.Orion.NetFlow.Service.Program - NetFlowService will be abnormally terminated - Unhandled exception. 

System.IO.FileLoadException: Could not load file or assembly 'Solarwinds.Licensing.Framework'




This occurs when the Solarwinds.Licensing.Framework DLL file is missing from C:\Program Files (x86)\SolarWinds\Orion\NetFlowTrafficAnalysis


  1. Check the folder default path: C:\Program Files (x86)\SolarWinds\Orion\NetFlowTrafficAnalysis
  2. If this is missing, perform any of the following:
    • Open the Control Panel and repair NTA.
    • Run the NTA installer so the files can be updated and created.
