Overview

What Is vcruntime140_cor3.dll?

vcruntime140_cor3.dll is a Microsoft C Runtime Library file included with Microsoft® Visual Studio® and distributed as part of the Microsoft Visual C++ Runtime for .NET Core / .NET 5+ applications.

It is a variant of the standard vcruntime140.dll, adapted specifically for applications built on .NET Core, .NET 5/6/7+, and certain modern Visual Studio toolchains.

Verified Metadata:

  • Company: Microsoft Corporation
  • Product: Microsoft® Visual Studio®
  • Description: Microsoft® C Runtime Library
  • Architecture: Varies by application (x86 or x64)

This DLL is required by applications built using newer versions of the Microsoft C Runtime that target .NET Core–based distributions.

What vcruntime140_cor3.dll Is Used For

This runtime library provides foundational C/C++ runtime functionality for applications using:

  • .NET Core runtime bundles
  • Modern Visual Studio native components
  • Native modules compiled for .NET hosts
  • Cross-platform .NET components using native Windows interop

It supports:

  • Memory allocation and management
  • Exception handling
  • Standard C runtime operations
  • Native interop for .NET Core runtime components

If this DLL is missing, applications depending on these runtime features cannot start.

Where vcruntime140_cor3.dll Is Located

Legitimate copies come only from Microsoft installers and appear in:

  • Application installation directories that embed the runtime
  • Framework-dependent .NET Core / .NET apps containing native modules
  • Visual Studio and vcredist runtime folders

It is not a standard Windows system file and should not be manually placed in:

  • System32
  • SysWOW64
  • Arbitrary global folders

Each application includes the version it needs.

Common vcruntime140_cor3.dll Error Messages

The program can’t start because vcruntime140_cor3.dll is missing
vcruntime140_cor3.dll was not found
Error loading vcruntime140_cor3.dll
The code execution cannot proceed because vcruntime140_cor3.dll is missing

These errors appear when the required runtime was not installed correctly.

Why These Errors Occur

  • Application missing its bundled runtime files
  • Damaged or corrupted installation
  • Antivirus or cleanup tools removing the DLL
  • Using unpacked or portable versions missing dependencies
  • Incorrect or mismatched runtime for the application’s architecture

Because this DLL is tied to .NET Core–based applications, missing it often prevents startup entirely.

How To Fix vcruntime140_cor3.dll Errors

1. Reinstall or Repair the Application

The correct copy always comes with the application. Reinstalling ensures a matching version is restored.

2. Restore From Antivirus Quarantine

If the DLL was flagged:

  • Open antivirus or endpoint protection
  • Restore vcruntime140_cor3.dll if quarantined
  • Add the application folder to exclusions if necessary

3. Ensure Matching Architecture

Applications requiring x64 cannot use an x86 version, and vice versa. Make sure:

  • The app architecture matches the DLL architecture
  • The runtime folder wasn’t mixed between versions

4. Avoid Manual Replacement When Possible

This DLL is version-specific. Replacing it with a random copy from another program often results in compatibility issues.

If a manual restore is unavoidable, use:

  • The version bundled with the application, or
  • A verified matching version available on DLLme

Manual Installation Notes

For portable or unpacked .NET Core applications:

  • Place vcruntime140_cor3.dll in the same directory as the application's executable
  • Do not store it in Windows system folders

Reinstalling is still the recommended fix.

Summary

  • vcruntime140_cor3.dll is a Microsoft C Runtime Library variant used by .NET Core / modern Visual Studio applications.
  • It provides core C/C++ runtime services required for startup.
  • Errors occur when the application’s bundled runtime is missing, corrupted, or quarantined.
  • The correct fix is to reinstall or repair the application or restore the DLL from quarantine.

If you need a specific version of vcruntime140_cor3.dll, request it on the DLLme file page.

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_cor3.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_cor3.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_cor3.dll"

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

    regsvr32 vcruntime140_cor3.dll

How to Install vcruntime140_cor3.dll

To install vcruntime140_cor3.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_cor3.dll

Place 32-bit DLL files in:

C:\Windows\SysWOW64\vcruntime140_cor3.dll

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

C:\path\to\exe\vcruntime140_cor3.dll
