Problem: Some of the ArcGIS applications are not functioning properly
Under some circumstances, one or more of your ArcGIS desktop applications may not work properly, may crash frequently, or may fail to start completely.
The causes for such behavior may range from the accidental deletion of important components to incorrectly built customizations that may erroneously set or delete components.
Solution or Workaround
Warning: The instructions below include making changes to essential parts of your operating system. It is recommended that you backup your operating system and files, including the registry, before proceeding. Consult with a qualified computer systems professional, if necessary. Esri cannot guarantee results from incorrect modifications while following these instructions; therefore, use caution and proceed at your own risk.In most cases, uninstalling and reinstalling ArcGIS will resolve these problems. If the standard uninstall process does not clear up the problem, you should uninstall ArcGIS manually:
1. Unregister any custom commands you have installed.
How To: Register commands or classes in the Windows registry
2. Uninstall any additional custom components.
3. Run the clean up utility GroundZero.exe (found in arcgis\arcexe81\bin\). This will remove any registry keys that ArcGIS may have installed. If GroundZero has been removed by an unsuccessful uninstall process, you will need to contact ESRI Technical Support to obtain a copy.
4. Delete the arcexe81 folder and its contents.
Note: GroundZero.exe is automatically run when ArcGIS uninstalls properly.
