with latest changes r41720, r41721, r41722 in trunk,

the WinGrass7-installation should be started by grass70.py through
grass70.bat.

tested with WinGRASS-7.0.SVN-r41722-1-Setup.exe, WinGrass isn't starting.

in grass70.bat, there is

{{{
rem Path to the python directory
set PYTHONHOME=%GRASSDIR%\Python25
if "x%GRASS_PYTHON%" == "x" set GRASS_PYTHON=python
}}}

but python.exe is installed in C:\Program Files\GRASS-70-SVN\extrabin.
only python-dll, -include, -lib, -Libs are installed in
%GRASSDIR%\Python25.

so maybe PYTHONHOME should be changed?

best regards
Helmut

Comment (by hellik):

additionally I've seen in grass70.py

{{{
[...]
# Set the GISBASE variable
gisbase = "c:/osgeo4w/usr/src/grass_trunk/dist.i686-pc-mingw32"
cmd_name = "grass70"
grass_version = "7.0.svn"
ld_library_path_var = 'PATH'
config_projshare = "/c/OSGeo4W/share/proj"
grass_config_dirname = ".grass7"
[...]
}}}

gisbase and config_projshare should reflect the installation-folder (i.e.
C:\Program Files\GRASS-70-SVN)

No, we should just stop trying to "bundle" Python, and use the installer
instead.

FYI, I've searched through my WinVista32-box, there a few python copies on
my laptop, always shipped/bundled with a software (ArcGis 9.3, Scribus,
Inkscape, Osgeo4w,...).
