No valid license

If the following error comes up while opening the PowerShell Console or while loading the Snap-In, a valid license could not be obtained.


Attempting to perform the Start operation on the 'BlsEmdb' provider failed. Could not find license file '<Installation Path>\NwcServices.BlsAdministration.dll.lic'. A valid license cannot be granted for the type NwcServices.NWCLicenseManager.NWCLicenseProvider. Contact the manufacturer of the component for more information.


Please check:


  • If a license file exists in the same directory as the Snap-In-DLL "NwcServices.BlsAdministration.dll"?

  • If the license file is named "NwcServices.BlsAdministration.dll.lic"?

  • Open the license file with a text editor and check the expiry date (Attribute "LicenseExpiryDate")?

  • Check the count of clients in your DSM 2019.1 environment against the license (Attribute "MaximumClientCount")?


Please contact us if you can not solve the problem with the given hints.
