So recently I upgrade from Windows 8.1 to Windows 10 and faced one issue. Whenever I try to launch any game like Witcher 3 or Hatred I am getting msvcp120.dll is missing error. Even GTA 5 downloaded and installed by Steam gives me msvcp120.dll is missing error. I am sure that the problem is not in those games but in operating system, because until I upgraded to Windows 10 I could launch those games. Spending few hours on the Google I found that this error is related with Microsoft and there is easy way to fix msvcp120.dll is missing error in any application in Windows 10.
So I found that msvcp120.dll belongs to the Microsoft Visual Studio 2013 redistributable packages. The problem is that Microsoft Visual Studio 2013 redistributable packages are not compatible with Windows 10 yet. So, there are two options how to fix msvcp120.dll is missing error in Windows 10. First is to reinstall Windows 10 and you will have msvcp120.dll is the installation goes as intended. Second you can download and install genuine and compatible with Windows 10 msvcp120.dll from here: http://fix4dll.com/msvcp120_dll.
The second option fixed my msvcp120.dll is missing problems, hope it helps you too.
