I get the below error when I try to use grass processing from within QGIS. The error is given on all commands and I have got this error on 2 machines. I am using windows.
"This algorithm cannot be run 🙁
It seems that GRASS is not correctly installed and configured in your system. >Please install it before running GRASS algorithms."
I have tried downloading standalone GRASS 6.4.4 and changing the grass and mysys folder to that but no sucess.
Any help?

I worked this out for windows installs.
Once osgeo4w is installed, re-run osgeo4w setup and select advanced install.
Select the modules GRASS 6, GRASS 7 and mysys are selected for keep or install.
Once installed, in QGIS > processing options > manage providers > set paths accordingly e.g. '\OSGeo4W64\apps\grass\grass6'
This was quite trivial in the end, but it had caused me some headaches as this was automatically configured in previous osgeo4w installations.
