Why can I get the latest version of Gridgen to run after upgrading from V13?
You most likely still have V13 environment variables set, such as GRIDGEN_HOME. If the old environment variables from V13 are present, they can affect Gridgen’s ability to function. This is due to the fact that our latest version of Gridgen actually sets up the environment variables it needs at startup and unsets them at shutdown. If you find that you do have these environment variables set, please remove them. You may need to restart your machine once you have removed them.
