Hi Robert,

I realised that vtkpython.exe works, if I drag and drop my .py file on
it. Ie, running my .py file using vtkpython.exe
But my python interpreter does not work with the python file. I have
tried what you suggested.
Below is what I typed in command line, as well as the error that it

C:\Qt\VTKbin7\Wrapping\Python>python install
Traceback (most recent call last):
  File "", line 138, in <module>
    raise "ERROR: Must specify BUILD_TYPE=<config-name> on command
TypeError: exceptions must be classes or instances, not str

Is it just a small error with input format or something?

Thanks so much!
