I had the same problem and tried a few options, including downloading the wheels version and pip failed the same way/same error as you have. The solution for me was copying both rc.exe and rcdll.dll from
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
to
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin
Successfully installed now. Hope that helps.

I discovered that you can download Twisted wheels from http://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
Choose Twisted version, Python version, and OS version.
Download the wheel and install from local file with:
pip install path\to\Twisted-17.9.0-cp36-cp36m-win_amd64.whl
Twisted should then install successfully.
