The vcruntime140.dll file belongs to Microsoft’s Visual C++ runtime libraries. Programs built with Visual Studio require this component to run. Windows displays an error when the file cannot be located or has been damaged.
Understanding VCRuntime DLL Files
Dynamic Link Libraries contain code that multiple programs can share. This reduces file duplication and saves disk space. Windows applications reference these libraries during execution.
The runtime package installs essential functions that Windows applications need. Games and complex software rely heavily on these libraries for graphics processing and core operations.
Common Causes of VCRuntime DLL Errors
Several factors can trigger this error:
- Missing or corrupted
vcruntime140.dllfile - Incomplete Visual C++ Redistributable installation
- Outdated Windows system files
- Registry corruption affecting DLL registration
- Conflicts between 32-bit and 64-bit library versions
Fix VCRuntime DLL Errors Using System File Checker
Windows includes a built-in repair tool that scans and fixes corrupted system files. Run this utility first before attempting other solutions.
Open Command Prompt with administrator rights:
- Press Windows + S
- Type “Command Prompt”
- Right-click the result and select “Run as administrator”
Execute the scan command:
sfc /scannowWait for the process to complete. The tool automatically repairs detected issues. Restart your computer after the scan finishes.
Reinstall Microsoft Visual C++ Redistributable
A fresh installation of the runtime package resolves most vcruntime140 dll error instances. Download the package directly from Microsoft’s official website.
Remove existing installations first:
- Open Settings using Windows + I
- Navigate to Apps
- Search for “Microsoft Visual C++ 2015-2022 Redistributable”
- Select each version and click Uninstall
Download both architecture versions from Microsoft:
| Architecture | File Name | When to Install |
|---|---|---|
| x86 (32-bit) | vc_redist.x86.exe | All Windows systems |
| x64 (64-bit) | vc_redist.x64.exe | 64-bit Windows only |
Install both packages even on 64-bit systems. Many applications still use 32-bit libraries.
Register the DLL File Manually
Registration problems can prevent Windows from accessing the library file. Manual registration updates the system registry with correct file locations.
Open Command Prompt as administrator and run:
regsvr32 vcruntime140.dllA confirmation dialog appears when registration succeeds. Restart your computer to apply the changes.
Run DISM to Repair System Image
Deployment Image Servicing and Management repairs the Windows system image. This tool fixes deeper corruption that System File Checker cannot resolve.
Execute DISM before running SFC:
DISM.exe /Online /Cleanup-image /RestorehealthThe process takes several minutes. Windows downloads replacement files from Microsoft servers during repair.
Run System File Checker after DISM completes:
sfc /scannowUpdate Windows to Fix VCRuntime DLL Errors
Microsoft distributes Visual C++ runtime updates through Windows Update. Missing patches can cause compatibility issues with newer applications.
Check for available updates:
- Open Settings
- Select Windows Update
- Click “Check for updates”
- Install all available updates
- Restart when prompted
Windows automatically installs security patches for runtime libraries. Keep your system current to prevent future errors.
Repair Visual C++ Package Without Reinstalling
The repair function fixes damaged installations without removing and reinstalling. This option saves time when files exist but have been corrupted.
Access the repair tool:
- Open Settings and navigate to Apps
- Locate “Microsoft Visual C++ 2015-2022 Redistributable”
- Click Modify
- Select Repair in the dialog window
- Wait for the process to finish
Restart your computer after repairs complete.
Preventing Future VCRuntime DLL Errors
Regular maintenance reduces the likelihood of encountering DLL errors. Keep your Windows installation updated with the latest security patches. Install software only from trusted sources to avoid corrupted installations.
Avoid modifying system files manually. Let Windows Update handle runtime library updates automatically. Run periodic System File Checker scans to catch corruption early.
Multiple Visual C++ versions can coexist without conflicts. Do not remove older versions unless specifically directed by software documentation.
FAQs
The vcruntime140.dll file provides runtime functions for programs developed with Microsoft Visual C++. Applications cannot start without this library when they require it.
Install the complete Visual C++ Redistributable package instead of downloading individual files. Standalone DLL downloads from third-party sites often contain malware.
System updates can overwrite or remove runtime files. Windows Update sometimes fails to reinstall required Visual C++ components, causing applications to fail.
Install both versions on 64-bit Windows systems. Many applications still use 32-bit libraries even when running on 64-bit operating systems.
Reinstall the Visual C++ Redistributable package for your system architecture. Most games automatically install required libraries, but manual installation fixes missing files.
