Unable to install on Windows

[S0mbre]

I was unable to install the lib on Windows 10 x64, either with or without the Cython flag.
Here's the full setup log:

I, too, am confused a little bit by the cython flag. On all the systems I've installed this on the build process always seems to recompile, which makes the GCC version or numpy or cython version really critical to success.

Have you tried installing specific versions of Numpy/Cython like?:
numpy==1.14.3
cython==0.28.2
