[osgeo4w-dev] Can't start nviz

[klo]

Hi,

while trying to run nviz from qgis grass toolbox, I get this error:

========================================
Application initialization failed
Can't find a usable init.tcl in the following directories:
     C:/OSGeo4W/apps/Python27/lib/tcl8.5
     C:/OSGeo4W/apps/grass/GRASS-~1.3RC/etc/lib/tcl8.5
     C:/OSGeo4W/apps/grass/GRASS-~1.3RC/lib/tcl8.5
     C:/OSGeo4W/apps/grass/GRASS-~1.3RC/etc/library
     C:/OSGeo4W/apps/grass/GRASS-~1.3RC/library
     C:/OSGeo4W/apps/grass/GRASS-~1.3RC/tcl8.5.2/library
     C:/OSGeo4W/apps/grass/tcl8.5.2/library

This probably means that Tcl wasn't installed properly.
========================================


File init.tcl can be found as  
C:\OSGeo4W\apps\grass\grass-6.4.3RC1\bwidget\init.tcl

Any resolution advice?
