Hello Ramachandran,

You can see that the error has changed from
> ImportError: No module named vmtk
to
> ImportError: No module named vtk

so the VMTK python module can now be found, but the vtk python module
can not be found by the vmtk-commanline-script.

In your PYTHONPATH I see:
    "C:\Program Files\VTK\lib\vtk-5.2"
I do think that you should change this to:
    "C:\Program Files\VTK\lib\site-packages"
as you have to tell python where to find the directory 'vtk' which
contains the necessary python scripts (e.g. 'rendering.py', etc.)

good luck,
Hugo
