To rest Nigel AI login credentials or log out:

 

  1. Restart the computer to clear the memory of NI background processes and services.
  2. Delete the following (if they exist):

    • C:\Users\<username>\AppData\Local\National Instruments\NigelLocalService\ProtectedStore.dat 

    • Log files in: %programdata%\National Instruments\AIAssistants\Logs

    • If using LabVIEW:

      • 64-bit:  

        • C:\Users\<username>\AppData\Local\National Instruments\LabVIEW <Version number> x64\LabVIEW Nigel Chat Application

      • 32-bit:
        • C:\Users\<username>\AppData\Local\National Instruments\LabVIEW <Version number> x86\LabVIEW Nigel Chat Application

You may need to restart the computer again.
