MSVCP140.dll is missing

What is MSVCP140-DLL-MISSING?

MSVCP140-DLL-MISSING shows up as a medium-severity software runtime fault. 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. This usually traces back to DLL accidentally deleted and antivirus quarantined the file. Use the steps below to track down and fix the cause.

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
  Check antivirus quarantine for MSVCP140.dll

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

• 3
  Run sfc /scannow to restore system DLLs

  Try "Run sfc /scannow to restore system DLLs" next if the issue persists — it addresses a secondary cause.
