Crash on startup directly after install (wrong copy of python dll picked up)

Debug information from console for GRASS 6.4.0 RC6 x64:

# Begin Shell output

Cleaning up temporary files ... Starting GRASS ... Traceback (most recent call last):

File "e:/GRASS-64/etc/wxpython/gis_set.py", line 863, in <module>

ImportError: DLL load failed: The specified procedure could not be found. Error in GUI startup. If necessary, please report this error to the GRASS developers. Switching to text mode now.

GUI Window says: python.exe - Entry Point Not Found "The procedure entry point ?PyWinObject_AsHANDLE@@YAHPAU_object@@PAPAX@Z could not be located in the dynamic link library pywintypes25.dll."

# end pop-up window output

I do have Python 2.6 x86_64 installed on my Vista x64 Ultimate workstation, I do not know if that makes a difference. I also have cygwin (latest with almost every library in the Path environmental var), MinGW32 and 64 in the Path var. I do not know if that makes any difference, but I wanted to give all the possible installs that could be interfering with GRASS. Last note is that the TCL/TK GUI works great.

slightly more foolproof version of the patch applied in devbr6 as r55765.

I'm not sure if the default for %GRASS_PYTHON% should be "python.exe" or if just "python" is ok. After that is known I think it's ok to backport to relbr64.

Since it was "python" before it seems to be acceptable.

I have downloaded latest winGRASS-devbr (r55765) and it starts fine including the GUI. Please backport.

ok, thanks. backport done w/ r55776.

wrt testing, note to be careful that (IIRC) init.bat is not used in all wingrass startup modes.

reopen if needed.
