Hi Troels, I'm looking at replicating your setup in a virtual machine, but there is one piece of information missing. Did you use Anaconda (http://continuum.io) or Enthought Python Distribution (EPD, https://www.enthought.com/canopy-express/) in combination with IPython? This might be where the problem lies, one of these might not be compatible with compiling the C modules or may require settings to be changes to allow it to run with the MSVS compilers.
