A MSVCP140.dll-specific sequence based on Visual C++ Runtime and its supported delivery through Visual C++ v14 Redistributable.
Record the affected program, exact MSVCP140.dll message, Windows version, and whether the app is 32-bit or 64-bit.
MSVCP140.dll must follow the program architecture—not merely the Windows architecture.
Open Settings > Apps > Installed apps. Find the supported Microsoft Visual C++ Redistributable, open More options, choose Modify, and select Repair in Microsoft Visual C++ Setup. If it is absent, install the official package matching the application's architecture.
□ Restart Windows after the supported repair
□ Launch the same affected program
□ Confirm the original MSVCP140.dll message is gone
□ If it remains, record the new exact error before continuing
Restart Windows after the supported repair, launch the same affected program, and repeat the action that produced the original message. If MSVCP140.dll still fails, record the new exact error and stop before making unrelated system changes.
Safety warning: Do not copy or register MSVCP140.dll in isolation. No. MSVCP140.dll is serviced as part of the Visual C++ runtime package and is not repaired by registering it as a COM component. Repair the Redistributable instead.
A Microsoft Visual C++ standard-library runtime component used by many Windows applications. It is normally installed with an application or through a supported Microsoft Visual C++ Redistributable package.
MSVCP140.dll is a Microsoft Visual C++ runtime library that provides C++ standard-library functions used by applications compiled with supported Visual Studio toolsets. It is commonly installed by the application or by a Microsoft Visual C++ Redistributable package.
Use the official application or Microsoft package.
Match the affected program and x86 / x64 / ARM64 architecture before repairing.
Repair the application or Redistributable before using Windows system-file tools.
Capture the new wording and affected program. Do not continue repeating unrelated repairs.
This decision path is specific to Microsoft C++ Runtime Library. A Microsoft Visual C++ standard-library runtime component used by many Windows applications. It is normally installed with an application or through a supported Microsoft Visual C++ Redistributable package.
Note the affected program, the action that triggered the failure, and what changed immediately beforehand. Save open work and close that program normally; use Task Manager only if it is frozen or the supported repair tool says it is still running.
Record the exact message “MSVCP140.dll was not found” before closing it.Determine whether the reporting program is 32-bit or 64-bit before changing Visual C++ v14 Redistributable. A 64-bit edition of Windows can still run an x86 application, so Windows architecture alone does not identify the required runtime.
Dependency clue: vcruntime140.dll — Runtime dependency.Repair or reinstall the application reporting the error. Then install or repair Microsoft's supported Visual C++ Redistributable for the application architecture. Use Repair or Change only when Windows or the official installer actually offers that option.
Use the official Visual C++ v14 Redistributable installer and retain its x86 / x64 / ARM64 packages when the affected software needs them.Restart Windows and test the application again. Launch the same program and repeat the original action. If the wording changes, capture the new error and reassess instead of repeating unrelated repairs.
Validation target: The required Visual C++ Redistributable is absent or damaged.Page-specific safety boundary: MSVCP140.dll must remain version-compatible with vcruntime140.dll. Reset only after backing up application data, and reinstall solely from the program publisher or Microsoft.
Versions, hashes, and signatures can vary by supported package release. This report does not invent a universal "latest file" value. Confirm package selection against Latest supported Visual C++ Redistributable downloads (Microsoft Learn).
Distinct locally observed specimens are deduplicated by version, architecture, and SHA-256. A signature result identifies the inspected file; it is not a recommendation to copy a loose DLL into Windows.
Evidence method: file metadata read from the observed specimen, SHA-256 calculated by WinLab, and digital-signature status checked through Windows Authenticode. Observed 2026-08-31.
How we use AI: AI helps draft clear answers, but every published technical claim must be tied to an approved source, pass safety checks, and receive editorial review. It may not invent versions, hashes, signatures, download links, or success rates.
MSVCP140.dll is a Microsoft Visual C++ runtime library that provides C++ standard-library functions used by applications compiled with supported Visual Studio toolsets. It is commonly installed by the application or by a Microsoft Visual C++ Redistributable package.
The application's supported Visual C++ Redistributable may not be installed, the package may be damaged, the application setup may be incomplete, or the wrong runtime architecture may be present.
Repair the affected application and then install or repair Microsoft's supported Visual C++ Redistributable that matches the application architecture. Avoid copying a loose DLL into Windows folders.
MSVCP140.dll supplies C++ standard-library code to the calling application, so its architecture follows that application. A 32-bit program needs the x86 runtime even when Windows itself is 64-bit.
No. Use the program's installer or Microsoft's supported Visual C++ Redistributable. That preserves the compatible MSVCP140.dll build alongside VCRUNTIME and Universal CRT dependencies.
No. MSVCP140.dll is serviced as part of the Visual C++ runtime package and is not repaired by registering it as a COM component. Repair the Redistributable instead.
