So, I am now attempting to actually learn C++, and I saw that in the “C++” tab of the Project browser, that I could install Visual Studio 2013 from there, so I tried, and, sure enough, a little “starting installation” thing appeared in the corner, went away, and nothing happened.
I’m curious why it was there, when it appears to do nothing. (or at least doesn’t do what it says)
Take a look at this thread: https://forums.unrealengine/showthread.php?83009-Whenever-I-press-quot-Install-Visual-Studio-2013-quot-it-says-quot-starting-installation-quot-but-nothing-happens 
Thanks, this did indeed help.
