GIS Systems Architecture Team Date: April 17, 2026 Version: 2.0 Executive Summary The error message “An ArcGIS Pro Advanced Concurrent Use license is not authorized” represents a critical failure in the license brokering chain between the ArcGIS Pro client, the License Manager (ArcGIS License Manager 202x), and the Esri authorization servers. In enterprise environments, this error halts productivity for GIS professionals who rely on shared, floating license pools. This paper provides a systematic diagnostic taxonomy, root cause analysis, and remediation protocol. It addresses licensing architecture, common failure modes (network, version mismatch, feature code absence, license borrowing corruption), and preventive monitoring strategies. 1. Introduction ArcGIS Pro, Esri’s flagship 64-bit desktop GIS, operates under three primary licensing models: Named User (Portal-based), Single Use (file-based), and Concurrent Use (floating). The concurrent use model is preferred in large organizations because it allows a limited number of licenses (e.g., 25 Advanced seats) to be shared dynamically among many users. | 12% | | R4 | Network/Port Blocking
