In QGIS 2.12 and down, when one went about manually setting the GRASS provider folder paths, this was the way to do it
In GIS 2.14 there is no Msys folder in the same path (...\apps\msys) or any other folder in the QGIS installation.
So even though QGIS standalone needs to have it set correctly in order for GRASS tools to work, it can't be done.
So how do you make GRASS tools work in QGIS 2.14?
