This Dynamic Link Library allows Windows systems to execute C++ code. It's part of Microsoft Visual Studio. While it has no standalone features, the programme is essential for several third-party apps.
Smooth C++ library
MSVCP140 is a DLL (Dynamic Link Library) developed by Microsoft. It's packaged along with the Microsoft Visual Studio files. It provides necessary components for executing C++ apps.
In most situations, the DLL will already be on your Windows computer. However, if MSVCP140 is missing, deleted or corrupted in some way, you can face troublesome error messages. Fortunately, it's a free license file available directly from Microsoft.
MSVCP140 doesn't actually have any visible interface. End-users are not its aims. It simply provides back-end features essential to apps and games built on Visual C++.
You will only run into this DLL in error message prompts. The installation of MSVCP140 is fairly straightforward as part of the Microsoft Visual Studio Redistributable Package.
In terms of security, this dynamic library poses a very low risk. It's not a system file. Additionally, it's provided directly by Microsoft, along with MD5 security checksums. There are some instances of this DLL name being used by trojans, though.
Microsoft provides two versions of this DLL: a 32-bit version for x86 system and a 64-bit version for x64 system. x86 systems will only need the 32-bit version. x64 systems should download both MSVCP140.dll versions.
Essential C++ runtime library
As part of the Windows infrastructure, MSVCP140 is a subtle dynamic library. You can go a lifetime without ever coming across it. However, many games and apps will need you to install or reinstall this DLL file to properly function. If that's ever the case, you can make sure you download the Visual Studio Redistributable Package.
