My guess is that the GDAL data files aren't being picked up
These are installed in a well known location on Nix so they
Are easily picked up this isn't necessarily so on Windows
One can tell the system where the data files are with the following
Environment Variables
GDAL_DATA = $ROOT_OF_GDAL_DATA_FILES # /usr/local/share/gdal normally on
Nix
PROJ_LIB = $ROOT_OF_PROJ_DATA_FILES # /usr/local/share/proj normally on
Nix
