Unable to Install Visual Studio 2013 on Computer with Visual Studio 2015

Question

I have a Windows 8.1 computer with Visual Studio Community 2015 installed and no other version of Visual Studio. I want to install Visual Studio Community 2013 because this is required to use C++ with Unreal Engine 4. But I get this error message when I try to install.

So I restarted my computer, and the same error message still shows up. I have tried installing from an executable from the Visual Studio webpage, and from a button in Unreal Engine 4 that opens the Visual Studio 2013 installer. What could be the problem? Thanks.

From memory, you're supposed to be able to install multiple versions of visual studio, provided you install them chronologically.

Make a backup. Then try uninstalling VS 2015. Then installing VS 2013, then re-installing VS 2015.

Better yet, do this in a virtual machine. - Additionally; A virtual machine will allow you to install VS 2013 in isolation, so that you won't need to uninstall VS 2015.
