I had the same problem in Visual Studio Pro 2017: missing MSVCP120.dll file in Release mode and missing MSVCP120d.dll file in Debug mode. I installed Visual C++ Redistributable Packages for Visual Studio 2013 and Update for Visual C++ 2013 and Visual C++ Redistributable Package as suggested here Microsoft answer this fixed the release mode. For the debug mode what eventually worked was to copy msvcp120d.dll and msvcr120d.dll from a different computer (with Visual studio 2013) into C:\Windows\System32
