Overview

What Is vcruntime140.dll?

vcruntime140.dll is an official Microsoft runtime file that ships with the Microsoft Visual C++ 2015–2022 Redistributable (also called MSVC 14.x).

It contains core C runtime functions used by applications built with:

  • Visual Studio 2015
  • Visual Studio 2017
  • Visual Studio 2019
  • Visual Studio 2022

The DLL is required by hundreds of thousands of Windows applications, including:

  • Games (Unity, Unreal, Frostbite, Source, etc.)
  • Adobe and Autodesk products
  • Discord, OBS, Steam tools
  • Business and engineering applications
  • Custom software built using MSVC 14.x

On DLLme, all Verified files for this DLL are official Microsoft-signed binaries.

What Does vcruntime140.dll Do?

This DLL contains essential C Runtime (CRT) functions needed for running programs compiled with the MSVC 14.x toolchain.

It provides:

✔ Runtime Support Functions

Program startup logic, core runtime initialization, memory functions.

✔ Exception Handling

Structured exception handling and runtime error processing.

✔ Threading Helpers

Basic thread management and synchronization components.

✔ Standard C Functions

String handling, memory operations, error reporting, utility functions.

Applications built with MSVC cannot run without this DLL.

What Software Uses This DLL?

Any software compiled with Microsoft Visual Studio 2015–2022 may require this DLL. Common categories include:

  • Modern PC games
  • Adobe Creative Cloud applications
  • Engineering/CAD tools
  • Python distributions for Windows
  • Node.js, PHP, Ruby, and other language runtimes
  • OBS Studio and media tools
  • Proprietary enterprise software

If an application depends on the Visual C++ 2015–2022 runtime, it must load vcruntime140.dll at startup.

Common Error Messages

If the DLL is missing or corrupted, users typically see:

“vcruntime140.dll is missing.”
“The program can’t start because vcruntime140.dll was not found.”
“Error loading vcruntime140.dll.”
“vcruntime140.dll is corrupted or not designed to run on Windows.”

These errors only mean the Visual C++ runtime isn't installed correctly.

Why Errors Occur

Typical causes include:

  • The Visual C++ 2015–2022 Redistributable was never installed
  • The DLL was removed or corrupted
  • Incorrect architecture (program expects x86 but only x64 is installed)
  • A software update installed a newer VC++ version, breaking an older dependency
  • Antivirus quarantined the DLL
  • The application shipped without redistributables

Programs cannot replace this file manually—they require the full runtime package.

Is vcruntime140.dll Safe?

Yes — when it comes from:

  • Microsoft’s official Visual C++ Redistributable
  • Windows Update
  • Verified DLLme entries
  • The original software installer

Microsoft always signs this DLL, and verified copies match the official hash values.

How to Fix Errors With vcruntime140.dll

Because this is an official Microsoft system component, the solution is straightforward:

1. Install (or reinstall) the Microsoft Visual C++ 2015–2022 Redistributable

Install both:

  • vcredist_x86.exe
  • vcredist_x64.exe

Even on 64-bit Windows, many apps require the 32-bit version.

2. Repair the Runtime

If already installed, open Apps & Features, select the runtime, and click Repair.

3. Restore Quarantined Files

If antivirus software removed the DLL, restore it and whitelist the application.

4. Keep Architectures Matched

  • 32-bit apps require the x86 DLL
  • 64-bit apps require the x64 DLL

5. Avoid downloading standalone DLL copies

These runtimes rely on multiple matching components. Using only a single DLL rarely fixes anything and can introduce further errors.

File Location

After installing the redistributable, Windows places vcruntime140.dll in:

  • C:\Windows\System32 (64-bit version)
  • C:\Windows\SysWOW64 (32-bit version)

Applications may also include private copies inside:

  • AppFolder\
  • AppFolder\bin\
  • GameFolder\Binaries\Win32\
  • GameFolder\Binaries\Win64\

These are application-specific locations created by installers.

Summary

  • vcruntime140.dll is a core Microsoft runtime file from the Visual C++ 2015–2022 Redistributable.
  • Required by thousands of modern Windows applications and games.
  • Missing DLL errors occur when the redistributable is not installed or becomes corrupted.
  • The correct fix is installing or repairing the official VC++ 2015–2022 Redistributables (both x86 / x64).
  • Verified DLLme versions are authentic Microsoft-signed builds.

Fixes and Solutions

The first step in resolving DLL errors is to completely uninstall the affected software and reinstall its latest version. We know this does not always solve the problem, which is why DLLme exists. If reinstalling the application does not help, or if you are unsure which app is causing the error, follow the steps below. These are the most common solutions for fixing vcruntime140.dll errors.

  • Repair Windows: Make sure Windows is fully updated, then open Windows Terminal or PowerShell as an administrator (search for “PowerShell” in the Start menu, right-click it, and choose “Run as administrator”). This allows you to repair the Windows component store and run the System File Checker (SFC).

    Repair the Windows component store so SFC can pull clean files:

    DISM /Online /Cleanup-Image /RestoreHealth

    Scan all protected system files and automatically repair problems:

    sfc /scannow
  • Uninstall & Reinstall: On this DLL page, check the Company/Product section to identify the related app, then fully uninstall it. If you plan to continue using it, reinstall the latest version. Be sure to save or back up any important data before uninstalling. Windows or antivirus software may sometimes quarantine DLL files, especially if the DLL is unfamiliar or appears suspicious. Check your antivirus quarantine or logs to determine if this is the cause of your issue.
  • Download the DLL: Download the latest 32-bit or 64-bit version of the DLL directly from our repository using the download button above. Most users will need the 64-bit version, but if you are unsure, or if a 64-bit version is not available, you can install both the 32-bit and 64-bit DLLs. DLLme verifies DLLs that come from our admins, partners, and trusted affiliates. User-uploaded files may be verified later if a trusted source is confirmed.
  • Register the DLL: Most DLL files do not need registration, but some DLLs are COM components and must be registered to work correctly. If registration is required, open Windows Terminal or PowerShell as an administrator.

    Register the DLL (you can also drag the DLL file into the window to automatically fill in its full path): 

    regsvr32 "C:\path\to\vcruntime140.dll"

    If you are registering a 32-bit DLL on 64-bit Windows, use the 32-bit RegSvr32: 

    C:\Windows\SysWOW64\regsvr32 "C:\path\to\vcruntime140.dll"

    Or open Windows Terminal/PowerShell in the DLL’s folder and run: 

    regsvr32 vcruntime140.dll

How to Install vcruntime140.dll

To install vcruntime140.dll, place the DLL file in the appropriate Windows system folder or in the same folder as the application’s .exe file. If you are not sure which version (32-bit or 64-bit) to use, you can safely install both.

On 64-bit versions of Windows, place 64-bit DLL files in:

C:\Windows\System32\vcruntime140.dll

Place 32-bit DLL files in:

C:\Windows\SysWOW64\vcruntime140.dll

Or place the DLL file next to the application’s .exe:

C:\path\to\exe\vcruntime140.dll
