[c++] MSVCP120d.dll missing

I have the same problem with you when I implement OpenCV 2.4.11 on VS 2015. I tried to solve this problem by three methods one by one but they didn't work:

  1. download MSVCP120.DLL online and add it to windows path and OpenCV bin file path
  2. install Visual C++ Redistributable Packages for Visual Studio 2013 both x86 and x86
  3. adjust Debug mode. Go to configuration > C/C++ > Code Generation > Runtime Library and select Multi-threaded Debug (/MTd)

Finally I solved this problem by reinstalling VS2015 with selecting all the options that can be installed, it takes a lot space but it really works.
