[Qgis-user] HELP Please: SAGA, GRASS 6 & 7, R, do not work in vers. 2.4 -. 2.8

[Bernd Vogelgesang]

Hi,

maybe your paths are mixed up from all those different updates and  
versions you installed.
 From my experience, updating versions of QGIS rarely runs smoothly, so I  
always make "tabula rasa".
Under Windows, I uninstall everything connected with QGIS remove/rename  
the .qgis2 folder and delete all registry entries of QGIS with regedit.

When reinstalling, I found the OSGEO4W-installer with advanced install  
mode had the best results (but harder to understand).

If you want to go this way, be sure to write down all the plugins you  
would like to have, save own scripts or model etc. to a safe place.

You might still have problems when your paths in the Windows enviroment  
variables are twisted as well.

Just my 2cents. If other know better ways to solve those problems, please  
comment.

Cheers
Bernd
