[Qgis-user] Tools of Grass and SAGA do not work

Thu Apr 10 14:31:40 PDT 2014

Hi!

Thanks all for your support. 

Both GRASS and SAGA are provided by the standalone version of QGIS 2.2. 

As if that were a problem in my computer, I installed the program on two computers, one with XP and one with Vista. With XP works perfectly. In Vista, I getthe same errors. So I guess the problem must be in the OS. 
The Python console also gives errors when run. Can it be related?

"No se pudo abrir la consola de Python:

Traceback (most recent call last):
  File "", line 2, in 
  File "C:/PROGRA~1/QGISVA~1/apps/qgis/./python\console\console.py", line 43, in show_console
    _console = PythonConsole( parent )

Can it be related?
GRAAS and SAGA are disabled in the configuration of the processing tab. 

Are there any known problems with this version of QGIS and Vista? Is installing another version could solve? 

Thanks
