By the way, if you have already downloaded this file from a third-party site, it is possible that you will see an error message that the MSVCP120.DLL program is not intended for execution in Windows 7 (8, 10) or contains an error. So that such an error does not appear, again, you should download the file from the official site. See also: How to download msvcp140.dll for Windows 7, 8 and Windows 10.
What is msvcp120.dll and how to download it from Microsoft
The MSVCP120.DLL file is a component (library) of Microsoft Visual Studio 2013, which is necessary to run some programs and games developed using this environment.
On the computer, this file is in Windows / System32 and Windows / SYSWOW64 folders (for x64 versions of Windows). In some cases, it can also be needed in the root folder of the game or a program that does not start. This is the answer to the question where you throw msvcp120.dll if you downloaded it from a third-party site, but I do not recommend this option, besides, it will hardly help correct the situation: the text of the error message will simply change, and another file that is not grabs.
To download the disseminated Microsoft Visual Studio 2013 packets, go to the official Microsoft Download Center page http://www.microsoft.com/ru-ru/download/details.aspx?id=40784 and click the "Download" button. Upgrade 2017: Now the download is also available on the https://support.microsoft.com/ru-ur/help/3179560/update-for-visual-c-2013-for-visual-c-redistributable-c-redistributable-package (at the bottom of the page) .
After downloading, install these components and restart the computer. Most likely, the error "Starting the program is impossible, since MSVCP120.dll is missing on the computer" will disappear. If this does not happen, try copying this file from the System32 folder (and it is already there for sure after installing the distributed Visual C ++ packages 2013) in the root folder of the game or program.
Important: If you have a 64-bit system, then x64 and x86 (32-bit) of the version of the package distributed, since most programs require 32-bit DLL, regardless of the system's bit.
