No license for LonWorks communication error when using a non LE dongle.


"No license for LonWorks communication" error when using a non LE dongle.

Product Line

TAC Vista


  • Non LE dongle (LE= Limited Edition which has no Webstation or multiserver functionality)
  • Aladdin Privilege Administrator 2.01
  • Vista IV Licensing


One would normally expect this error message when trying to run Webstation server with a Vista LE license. If the system is not using a Vista LE dongle/license, but the error "No license for LonWorks communication" appears, then the problem may be in the Privilege Server service.


  1. Shut down Vista Server and Workstation.
  2. Right click on My Computer and select Manage.
  3. Expand Services and Applications.
  4. Click on Services.
  5. Find the service Privilege Win32 Server.
  6. Right click on the service and select Stop.
  7. Right click on the service once more and select Start.
  8. Restart Vista Server and Workstation and verify that the error went away.
