The error message says that Windows SDK version 8,1 is needed, which I think is for Win8 originally. So one solution is to install the SDK and retry, and it may work.
I have a very similar problem, and have gone through python 3->python 2 and a similar Win SDK issue. But some other new problems appear… And I finally decide to go back to Atom 1.38.2, which works ok for me.
