MSVCP140.dll is missing

What is MSVCP140-DLL-MISSING?

MSVCP140.dll is the C++ Standard Library implementation distributed as part of the Microsoft Visual C++ 2015-2022 Redistributable. Applications compiled with MSVC need this DLL for STL containers, algorithms, streams, and other C++ standard library features. Its absence blocks application launch entirely.

Common Causes

• Visual C++ 2015-2022 Redistributable not installed
• DLL accidentally deleted
• Antivirus quarantined the file

Step-by-Step Fix Guide

• 1
  Install Visual C++ 2015-2022 Redistributable from Microsoft

  Downloading and installing the Visual C++ Redistributable from Microsoft is the safest and most reliable fix — never download individual DLL files from third-party websites.

• 2

  If the DLL was quarantined by antivirus, restore it from quarantine and add an exclusion for the Windows System32 directory.
