@milindk you installed pythonnet for python 2.7, but you need pythonnet built for python 3.6:

@denfromufa I have run into the same issue, running Windows 10, python3.6, and the current version of pythonnet from github. I confirmed that python3.6 is in my PATH, and is set as my environment on Visual Studio. After building from source, I tried running nPython.exe, and got the same error seen above.

Did you read the troubleshooting wiki?

@denfromufa switching to the ReleaseWinPY3 build config worked, thanks!
