[Paraview] Importing paraview.simple in external python environment

[livia.barazzetti at istb.unibe.ch]

Thank you for the response. 
I tried to change the PATH variable in windows but I had the same error.
 As a workaround,  I am changing my current directory (os.chdir('C:\\Program Files (x86)\\ParaView 4.0.1\\bin'))  before importing (successfully)  .
I don't know if maybe this depends on some configuration problem on my machine. 
Best regards
Livia

I believe you need to set you PATH environment variable to include the bin directory where all the dlls are.
