PROBLEM
When upgrading ArcGIS Desktop, the upgrade process fails, returning no error messages. Launching ArcGIS Administrator and navigating to the machine details window displays missing UMN IDs. A machine's UMN ID is important information, as it is used to facilitate the recovery of lost licenses, and to create Esri Secure License Files (ESLF)
When upgrading ArcGIS Desktop, the installer stops the FNPLicensingService to allow the installation to proceed smoothly. However, when FNPLicensingService is in use by other third-party software, the installer is prevented from stopping the service. This prevents the installer from upgrading ArcGIS Desktop and FNPLicensingService.
Uninstall ArcGIS Desktop, and stop FNPLicensingService before reinstalling the software.
Note: Stopping the service may affect other programs utilizing it. Ensure all other programs are closed before performing the following workaround.
