We will need to start programming soon, so if you haven't already, now is the time to download Visual Studio, which is the integrated development environment that we will need to program the framework for our engine and game logic in C++. Luckily, Microsoft provides Visual Studio Community for free.

To download Visual Studio Community, go to https://www.visualstudio.com/ and download Community 2015. This will download the installer for Visual Studio. After it downloads, simply run the installer. Note that Visual Studio Community 2015 does not install C++ by default, so be sure that under Features, you are installing Visual C++, Common Tools for Visual C++ 2015, and Microsoft Foundation Classes for C++. If you do not have C++ installed, you will not be able to write or compile code written for UE4 in Visual Studio since UE4 is built on C++.
