Unable to Compile open C++ Templates

So I have tried to open up a simple Basic Code, C++ Template. But it simply refuses to compile (and thus open up)

Here are the errors I got. I tried to fix it by following these C11XX error fixes. Uninstalled-reinstalled VS 2013. Switched to VS 2015. Restarted PC. Nothing works.
Here are some specs.
Windows 8.1 -64bit-. VS 2015 Update 3. Tried 4.12 and 4.15 Preview 2.

Also TGIF everyone :wink:

Solved. Here is the answer.

But I understand that you were able to do it in UE 4.14? I guess it can be a bug from unstable UE 4.15 version.
