Current user is not licensed to access ArcGIS Workflow Manager server. Contact Administrator

Error Message

After installing ArcGIS Workflow Manager or when attempting to open a Workflow Manager item in the ArcGIS Enterprise environment, the following error is returned:

Error: 
Current user is not licensed to access Workflow Manager server. Please contact your Administrator.

Cause

• The incorrect license is assigned to the user in Portal for ArcGIS. For example, when assigning the license, they mistake ArcGIS Workflow Manager (Classic) for ArcGIS Workflow Manager, preventing the user from accessing ArcGIS Workflow Manager.

Note:
ArcGIS Workflow Manager (Classic) is set for deprecation in the last quarter of 2027. Esri recommends transitioning from ArcGIS Workflow Manager (Classic) to the service-based Workflow Manager. For more information, refer to ArcGIS Blog Announcement: Deprecation of ArcGIS Workflow Manager (Classic).

• The add-on license of the ArcGIS Pro extension is assigned instead of the user type extension for the ArcGIS Workflow Manager license in Portal for ArcGIS. This occurs when selecting the 'Add-on licenses' tab on the Organization page.

Solution or Workaround

Assign the Workflow Manager user type extension license to the user. Refer to Portal for ArcGIS: Configure user type extensions for further instructions. Ensure the correct ArcGIS Workflow Manager license is selected.

Note: 
The license requirement for the ArcGIS Workflow Manager user type extension is removed in ArcGIS Enterprise 11.2.
