I have installed gnuradio and uhd according to the directions given in the ettus wiki. When I try to run gnuradio-companion.py I get: C:\Users\Al\>gnuradio-companion.py Traceback : File “C:\Program Files\gnuradio\bin\gnuradio-companion.py”, line 22, in Import pygtk ImportError: No module named pygtk I tried explicitly adding the PATH to pygtk using Rapid Environment Editor but that didn’t work. Looking for suggestion. Thank you. Al ---

The pygtk installer should setup that stuff automatically. Did you see the post install instructions on that wiki page for the python dependencies? -josh
