[Discuss-gnuradio] Problem with SWIG on Windows

[Camera Parts]

Hi,

  I am new to GnuRadio. 

  I installed on Windows 8 using gnuradio_3.7.9.2_win64.msi.  I am looking for 
a simple example in order to test the installation. When I try to run 
mono_tone.py located in \share\gnuradio\examples\audio, I got an error saying 
"ImportError: DLL load failed: %1 is not a valid Win32 application."

  Could someone help? 

Thanks
  

C:\GNURadio-3.7\share\gnuradio\examples\audio>python mono_tone.py
