如何在python 3.4 - .whl文件中安装

I recently tried to re-install numpy for python 3.4, since I got a new computer, and am struggling. I am on windows 8.1, and from what I remember I previously used a .exe file that did everything for me. However, this time I was given a .whl file (apparently this is a "Wheel" file), which I cannot figure out how to install.I recently tried to re-install numpy for python
