I just upgraded from 10.2 to 10.5. I am having trouble with Geographic Coordinate System Transformation for the dataframe.
Right click the Data Frame and choose Properties. I ensure that the Coordinate systems Tab is selected.
I Click the Transformation Button on the bottom of the window to open the Geographic Coordinate System Transformation window.
I see my convert from and into populated correctly.
But the Using shows no available transformation.
Did something happen during the upgrade? Is there any way to fix it so that it will project on the fly?
