Yes.

The environment variables are set in the batch file which is used to
start GRASS.
PYTHONHOME should not be set, and there should be no references to the
bundled Python25 directory in PYTHONPATH or PATH.

Okay what I did now is to delete the python25 folder in the wingrass
installation (only that folder nothing else)
I checked the batchfile (grass64) which includes:
@echo off
rem #########################################################################
rem #
rem # File dynamically created by NSIS installer script;
rem #
rem #########################################################################
rem #
rem # GRASS Initialization
rem #
rem #########################################################################
rem Set GRASS Installation Directory Variable
set GISBASE=C:\Program Files (x86)\GRASS 6.4.1
set PATH=C:\Program Files\R\R-2.12.0\bin;%PATH%
call "%GISBASE%\etc\env.bat"
"%WINGISBASE%\etc\Init.bat" %*
In the envvariables in windows there is no PYTHONHOME and PYTHONPATH is set to
%GISBASE%\etc\python and GRASS_PYTHON is set to C:\Python27\python
If I try now to start winGRASS nothing happens...
did I miss something?
