Solution or Workaround

***Note: You will be making changes to your computer’s registry. Esri is not responsible for any incorrect changes made to the registry of your machine. Please make the changes under your own permission.

1) uninstall ArcGIS and all ArcGIS applications on the machine. Uninstall all Python programs from the list.

Close all ArcGIS Desktop applications (i.e. ArcMap, ArcCatalog, ArcScene, etc).
Run the uninstall for your Esri products via:

Control Panel > Programs > Programs and Features > select your ArcGIS product – right-click item > select uninstall/change and follow prompts choosing remove

2) Delete the following directories if they still exist:

C:\Users\*user-name*\AppData\Roaming\ESRI
C:\Users\*user-name*\AppData\Local\ESRI
C:\Program Files (x86)\ArcGIS
C:\Program Files (x86)\Common Files\ArcGIS
C:\Users\*user-name*\Documents\ArcGIS\AddIns\Desktop10.x

If the folder is hidden you will need to go into the view tab on your windows explorer interface > navigate your way to the show/hide panel and select Hidden Items. Directories like ‘AppData’ are by default hidden folders.

3) Open the registry editor (From Start type “Regedit”) and delete the following registry keys if they still exist.

Note: Please be aware that removing these following registry keys will remove the child items within the ESRI Key. So please take this into consideration if you have other ESRI software installed. If you do have other ESRI software listed under the ESRI key, then target the deletion of the ‘Desktop (version number)’ key

HKEY_CURRENT_USER\Software\ESRI
HKEY_LOCAL_MACHINE\SOFTWARE\ESRI
