When attempting to install an add-in in ArcMap using the Add-In Manager, the following error message displays:
"No GUI components found in this Add-In. Add-In version does not match."
This error occurs if the version stated in the Config.esriaddinx file is higher than the ArcGIS version installing the add-in.
Add-ins do not support backward compatibility; that is, if an add-in targets ArcGIS version 10.2.x, the add-in works in version 10.2.x or higher but not in version 10.1.x or lower.
The solution provided guides users on how to update the add-in version in Visual Studio using the source code of the add-in project.
