Corrupted or deleted DLL files
Outdated or missing Microsoft Visual C++ redistributable packages
Software conflicts or incomplete installations
Malware infections damaging system files
Incorrect system updates or registry issues

Troubleshooting Basic DLL Issues

Step 1: Restart your PC

Before diving into complex solutions, restart your computer. Windows sometimes resolves temporary glitches that may be causing the DLL error.

Step 2: Reinstall affected applications

If the error appears when launching a specific program or game, try reinstalling that software. This process replaces missing or corrupted files associated with the application.

Uninstall the app via Control Panel or Settings.
Download the latest installer from the official website.
Install the program again and check if the error persists.

Step 3: Run System File Checker (SFC)

The SFC tool scans Windows system files and repairs corrupted or missing ones, including DLLs.

Press Win + R, type cmd, then press Ctrl + Shift + Enter to open Command Prompt as Administrator.
Enter the command: bash sfc /scannow
Wait for the scan to complete. If issues are found, SFC will attempt to fix them automatically.
Restart your computer and see if the error is resolved.

Manual Repair Methods

If basic troubleshooting doesn't work, manual repair is necessary. These steps involve downloading the DLL file from trusted sources, registering it, or replacing corrupted files.

Step 4: Download `vcruntime140.dll` from official sources

Avoid unreliable third-party sites; instead, download the DLL from official Microsoft sources or by installing the latest Visual C++ Redistributable.

Visit the Microsoft Download Center
Download the appropriate Visual C++ Redistributable package for your system (x86 or x64).
Install the package; this will automatically install all necessary DLL files, including vcruntime140.dll.

Step 5: Register the DLL with RegSvr32

If the DLL exists but isn't registered properly, register it manually:

Open Command Prompt as Administrator.
Navigate to the folder containing vcruntime140.dll (usually C:\Windows\System32): bash cd C:\Windows\System32
Register the DLL: bash regsvr32 vcruntime140.dll
Wait for confirmation message, then restart your computer.

Step 6: Replace the DLL manually

If you have a healthy copy of vcruntime140.dll, you can replace the faulty version:

Copy the DLL file into C:\Windows\System32 (for 64-bit systems) or C:\Windows\SysWOW64 (for 32-bit systems).
Overwrite the existing file.
Register the DLL as described above.
Restart your computer and test the application.

Advanced Fixes Using System Tools

Sometimes, DLL errors persist due to deeper system issues. Use more advanced tools to repair Windows integrity and restore system stability.

Step 7: Run Deployment Image Servicing and Management (DISM)

Open Command Prompt as Administrator.
Execute: bash DISM /Online /Cleanup-Image /RestoreHealth
Wait until the process completes. This tool repairs Windows system images that may be corrupted.

Step 8: Use System Restore

If the error started after recent changes or updates, reverting to an earlier restore point can fix the problem:

Search for "System Restore" in Windows Search and open it.
Follow on-screen instructions to choose a restore point before the error appeared.
Confirm and let Windows restore your system to that point.

Step 9: Boot into Safe Mode

Booting into Safe Mode loads Windows with minimal drivers and services, helping diagnose software conflicts.

Open Settings > Update & Security > Recovery.
Under “Advanced Startup,” click "Restart now."
After restart, go to Troubleshoot > Advanced options > Startup Settings > Restart.
Press 4 for Safe Mode.
Test the application for DLL errors. If resolved, consider reinstalling or updating drivers and applications.

Prevention and Best Practices

Proactively prevent DLL errors with these reliable practices:

Regular Windows updates

Keep your Windows OS up to date with the latest patches and security fixes.
Go to Settings > Update & Security > Windows Update.

Driver updates

Update hardware drivers regularly, especially graphics and chipset drivers, to ensure compatibility with Windows updates and applications.
