When launching games or applications in Windows 11/10, users may encounter the error: “The code execution can’t proceed because mfc140u.dll was not found” or “The program can’t start because mfc140u.dll is missing from your computer”.
The mfc140u.dll file is a Microsoft development known as the MFCDLL Shared Library, part of Microsoft Visual Studio 2015.
Possible causes of the error include:
– Missing Microsoft Visual Studio 2015 components
– Outdated version of the file
– The file being blocked by antivirus software (if games or applications are downloaded from unofficial sources, the antivirus may quarantine mfc140u.dll)
This article explains how to download the original mfc140u.dll file and fix the error in Windows 11/10.
Location of mfc140u.dll
