The new version of ArcGIS Pro 2.1 allows for the install of ArcGIS_Coordinate_Systems_Data_Windows and ArcGIS_Pro_PerUser_Coordinate_Systems_Data. Do I need both of these, what's the difference? Any help is appreciated.
Starting at ArcGIS Pro 2.1 (per-machine / all users install) and ArcGIS Desktop/Server 10.6 can use the same ArcGIS Coordinate Systems Data installation. If you plan to use the per-user / one user version of ArcGIS Pro, you need to install the per-user ArcGIS Coordinate Systems Data setup.
The per-user install is often used when someone doesn't have administrative rights to the machine AKA super user access. In that case, we cannot install to the Program Files folder and instead need to install into the user's folder location.
