Hi all,
I’m brand new to UE and trying to follow a coding tutorial I couldn’t create a c++ project! I can create a blueprint project but can’t create a class there either! I’ve tried to reinstall the engine 2 times and reinstall visual studio 2015 and tried with VS 2013 with no success. Here’s the error:

The project could not be compiled. Would you like to open it in Visual Studio?

Any ideas?

I found solution:

Try to find the file WindowsPlatformCompilerSetup.h at the folder: C:\Program Files (x86)\Epic Games\4.12\Engine\Source\Runtime\Core\Public\Windows

after, open WindowsPlatformCompilerSetup.h and try to find(try CTRL + F) and delete these numbers on the error codes list: 4599 and add #pragma warning(disable : >4599) at the top of the file.
I’ll be happy if i’m helpful.

Yep, this is the correct solution. For shedding a little light, Unreal doesn’t support VS 2015 Update 3 yet. As that’s the only version available on the site, this is the current workaround until Epic integrates support for it.

After reinstalling every thing one more time, with an older version of VS2015, it worked. For someone coming from Unity, this is truly a huge disappointment with the engine, since I’m trying to run away from the aforementioned infamous bugs, lets just hope it gets better from now on.
