+Installing cx_Freeze with support for python 3.5 is annoying. Here are the steps (thanks https://github.com/sekrause/cx_Freeze-Wheels):
+
+* Download and install the Visual C++ Build Tools 2005 from http://go.microsoft.com/fwlink/?LinkId=691126. I downloaded `visualcppbuildtools_full.exe`.
+* Install the python wheel package: `pip install wheel`
+* Download a [snapshot](https://bitbucket.org/anthony_tuininga/cx_freeze/downloads) of the latest development version of cx_Freeze, extract it, and cd into the folder you extracted it to
+* Build the package: `python setup.py bdist_wheel`
+* Install it with pip: `pip install dist\cx_Freeze-5.0-cp35-cp35m-win32.whl`
