Trying to run my programs .exe but MFC1200.dll is missing

Hi All,

I am using Visual Studio 2013 Professional. I created a Win32 project, compiled and ran my code and everything was successful. I want to send my .exe file to a friend so that they can run my program without using visual studio, but when they try to open my .exe file it says that they are missing MFC1200.dll. 

So my question is, what do they need to download (the minimum amount required) so that they can run my program? 

Thanks,

Heather
