Hi,
Thank you for posting your query in Microsoft Community.
The msvcp120.dll is one of the dynamic link libraries from Microsoft Visual C++ 2013 Redistributable and is necessary for many modern games and programs to run.

The file is usually located in Windows’ System32 and/or SysWOW64 folders. The right and working way to download msvcp120.dll is to visit Microsoft’s website, get Visual С++ 2013 Redistributable from http://www.microsoft.com/en-us/download/details.aspx?id=40784 and install it.

Right after installation, the file will be copied to the right folders on your computer and registered within the operating system. So, you don’t have to search standalone downloads of this file for Windows 8 or 7 to fix msvcp120.dll is missing error.

In some cases the game or program that don’t run may need the msvcp120.dll in its root o “bin” folder, so if the error isn’t fixed, try to copy (not move) the file from your Windows\System32 there.
Hope this information is helpful. Please feel free to reply in case you face any other issues with Windows in future.
