Help!

That looks like a problem with your Visual Studio installation, not Unreal. How did you install Visual Studio? Perhaps try uninstalling Visual Studio and then using Unreal. It will prompt you to install Visual Studio in order to compile your C++ class, but also take control of the installation process so that the correct parts are included.

Solved!

If you have windows 7, you will need to remove the update kb:2882822
