ArcGIS Pro: Licensing configuration settings are locked. Please contact your organization's administrator

Error Message

When attempting to launch ArcGIS Pro with a Concurrent Use license, the launch fails and returns the following error message:

Error:
Licensing configuration settings are locked. Please contact your organization's administrator.

In some instances, the error message also returns when attempting to change the license level of the Concurrent Use license in ArcGIS Pro.

Cause

By default, installing ArcGIS Pro silently sets the LOCK_AUTH_SETTING key in the Registry Editor to True. When this parameter is set to true, the license configuration is disabled, and any changes required are blocked.
