How to Fix the vcruntime140_1.dll Missing Error
Use these methods one by one to resolve the error. You don’t need to try them all — just proceed down the list until the issue is fixed.
1. Install or Repair Microsoft Visual C++ Redistributable
This is the most reliable and safest method. Download and install the latest supported Microsoft Visual C++ Redistributable package from the official Microsoft website.
- Go to the official Microsoft Visual C++ Redistributables download page.
- Select the versions appropriate for your system (x86 for 32-bit, x64 for 64-bit).
- Download and install both if unsure which architecture your application requires.
- Restart your PC and try launching the program again.
2. Perform a System File Checker (SFC) Scan
This built-in Windows utility scans and repairs corrupted or missing system files, including DLLs.
- Press Windows Key + S and type Command Prompt.
- Right-click and choose Run as Administrator.
- Type
sfc /scannowand press Enter. - Wait for the process to complete and restart your computer afterward.
This method is particularly useful if the DLL was damaged or deleted by a system-level issue or malware.
3. Reinstall the Application That Shows the Error
Sometimes the issue is specific to one application. Try reinstalling the problematic software:
- Open Settings > Apps > Installed Apps.
- Find the application and click Uninstall.
- Restart your computer.
- Download and install the application from its official website.
Make sure that your installation isn’t blocked by antivirus software or restricted Windows permissions.
4. Update Windows
Keeping Windows updated is crucial for maintaining libraries, system files, and dependencies like Visual C++:
- Go to Settings > Windows Update.
- Click Check for updates.
- Install all available updates.
- After reboot, verify if the issue is resolved.
5. Avoid Downloading DLLs Individually
Important warning: While many websites offer direct DLL downloads, this is highly discouraged.
These sources can be unreliable and potentially inject malware into your system. Always rely on repairing or re-installing the entire Visual C++ package from Microsoft’s official website instead of downloading individual DLL files.
6. Use System Restore (Optional)
If the problem started after a recent change to your system (such as installing new software or drivers), using a System Restore point might help.
- Search for Create a restore point in the Start menu.
- Choose System Restore and follow the prompts.
- Select a restore point created before the error started.
7. Scan for Malware or Viruses
Malware infections can corrupt or delete DLL files. Run a full antivirus scan to rule out this possibility:
- Use a reputable antivirus software to run a complete scan.
- Use Malwarebytes or Windows Defender as an additional layer of protection.
After removing threats, reapply the Visual C++ installation and recheck the error.
Advanced Troubleshooting Tips
If none of the standard solutions work, consider these technical steps:
- Use Dependency Walker to analyze what DLLs an application requires.
- Check Event Viewer for error logs that might provide more information.
- If you’re a developer or IT administrator, recompile the application with statically-linked dependencies to avoid runtime library issues.
