"Unable to open NTV2 grid shift file. NTV2 datum conversions cannot be performed unless an NTV2 grid shift file is installed in the same folder/directory as this software". Does Golden Software have this grid shift file?
A: NTV2 datum conversions cannot be performed unless an NTV2 grid shift file is installed in the same folder/directory as the software. If you receive this message in response to your request to change the datum of a plot document or other drawing in the application program, it generally indicates that the grid shift file is missing, has not been properly installed, or you are running an older version of Didger. The most recent version of Didger does perform the NTV2 datum conversion.

NTV2 is the Canadian government's officially sanctioned method of converting Canadian map data from the old NAD27 datum to the NAD83 datum. NTV2 is based on a hierarchical database of interpolation grids of different resolutions for different regions of the country.
