Running Python scripts from within the ArcGIS Enterprise environment returns the following error message, "RuntimeError: The software is not authorized for use."

Workaround

1) Open Registry Editor again and in the path, HKEY_CURRENT_USER\Software\ESRI\ArcGISPro\Licensing, rename the string value SOFTWARE_CLASS_FN to something else.

2) Open the Windows Command window again and, run the script. There is no error now. However, ArcGIS Pro asks for the right license again and insert the string value in the registry.

Another way is to use another operating system user who does not use ArcGIS Pro.

Update: The issue is reproducible on-premise as well.
