Double-click the file to open the Esri ArcGIS Add-In Installation Utility window.
To continue, click Install Add-In. The add-in is copied to the default location and installed. A copy of the file remains in the location where you browsed to it.
If ArcGIS Pro is open, exit and restart the application. The add-in is now available for use.
Return to the add-in. Click Login and sign in with your EarthCache credentials.
Now you can seamlessly search for and acquire imagery, right within ArcGIS Pro.
