The FME Reprojection Grid Add-on contains reprojection grid files that are not
included in the Desktop installer (FME Server and Cloud come with the Grid
Add-on).

The latest Grid Add-on may be downloaded from
http://www.safe.com/support/support-resources/fme-downloads/beta/

It is not necessary to install a Grid Add-on that matches your FME build number;
Grid Add-ons are expected to be fully backwards compatible with older versions
of FME.  It is also safe to upgrade your Grid Add-on by installing a newer Grid
Add-on on top of an older one (see Troublshooting for how to handle overwrite
prompts).

Installation Instructions
=========================
Extract the .zip into the root of each FME installation that requires access to
the grid files.  This will require write permission to the FME install
directory.

Troubleshooting
=========================

If prompted during installation, choose to overwrite existing files unless you
only want to install additions to the Grid Add-on.  It is expected that grids
within the Add-on will almost never change, so overwriting and skipping will
typically result in the same files being present.

If your desired grid is not contained within the Grid Add-on, it means that the
grid must be downloaded directly from a 3rd party.
