A VCRUNTIME140.dll-specific sequence based on Visual C++ Runtime and its supported delivery through Visual C++ v14 Redistributable.
Record the affected program, exact VCRUNTIME140.dll message, Windows version, and whether the app is 32-bit or 64-bit.
Setup has detected an installed package.
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 VCRUNTIME140.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 VCRUNTIME140.dll still fails, record the new exact error and stop before making unrelated system changes.
Safety warning: Do not copy or register VCRUNTIME140.dll in isolation. No. VCRUNTIME140.dll is a C runtime component rather than a COM server intended for manual registration. Repair the application or its Visual C++ Redistributable package.
A Microsoft Visual C++ runtime component used by applications built with supported Visual Studio toolsets. Missing or damaged runtime packages can prevent programs and games from starting.
VCRUNTIME140.dll is part of Microsoft's Visual C++ runtime. Applications built with supported Visual Studio toolsets may rely on it for core C and C++ runtime functions. It is normally delivered with the application or through Microsoft's 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++ runtime component used by applications built with supported Visual Studio toolsets. Missing or damaged runtime packages can prevent programs and games from starting.
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 “VCRUNTIME140.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: msvcp140.dll — Runtime dependency.Repair or reinstall the affected application. 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.Apply current Windows updates. 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: VCRUNTIME140.dll must remain version-compatible with msvcp140.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.
VCRUNTIME140.dll is part of Microsoft's Visual C++ runtime. Applications built with supported Visual Studio toolsets may rely on it for core C and C++ runtime functions. It is normally delivered with the application or through Microsoft's Visual C++ Redistributable package.
The required Visual C++ Redistributable may be absent or damaged, the application installation may be incomplete, security software may have quarantined a file, or the app may be loading the wrong architecture. The message identifies a missing dependency; it does not prove that Windows itself is damaged.
Repair or reinstall the affected application first. Then install or repair Microsoft's supported Visual C++ Redistributable matching the application's architecture. Use Windows Update, and reserve DISM followed by SFC for signs of wider operating-system corruption.
VCRUNTIME140.dll must match the architecture of the program loading it. A 64-bit PC can run both 32-bit and 64-bit programs, so those applications can legitimately require separate x86 and x64 Visual C++ packages.
No. Restore VCRUNTIME140.dll through the affected program or Microsoft's supported Visual C++ v14 Redistributable so the runtime build, architecture, and companion components stay matched.
No. VCRUNTIME140.dll is a C runtime component rather than a COM server intended for manual registration. Repair the application or its Visual C++ Redistributable package.
