@SamoPP

@SamoPP there is a fix for this issue in this branch, but I have other issues in that PR related to mono/msbuild/nuget/travis-ci:

#698

HI @denfromufa , I'm having the exact same issue on my machine (Windows 10/64/py 3.7) when trying to install pythonnet. You said there is already a fix for this in this branch, though I don't know what that is and how do I fix it. Can you help me get this solved? I'm new to python and github it self so any clues would be nice.. ^^

@rdnobrega

@rdnobrega if you are new to python, it is probably just easier to use python 3.6 and upgrade later when python ecosystem has picked up considerably the new version 3.7.

you can install from PR branches according to wiki instructions:

https://github.com/pythonnet/pythonnet/wiki/Installation#github-installation-from-master-branch

on windows @cgohlke provides the unofficial wheels:

https://www.lfd.uci.edu/~gohlke/pythonlibs/#pythonnet

Thanks @denfromufa. I actually installed just fine on my old computer W8/32b/py36. However, i did not managed to install the py37 branch on my main computer. It gives this error:

I am trying to install from pull request but it looks like I do not know how (please see below). Can you please guide me on how to install from mentioned pull request. Thanks.
