What Causes VCRUNTIME140.dll Errors?

This error occurs when Windows can't locate or access the VCRUNTIME140.dll file, preventing apps from running. It's not critical to the OS but disrupts programs relying on Visual C++ libraries. Common triggers include corrupted files, incomplete installs, or outdated redistributables.

Proven Fixes for VCRUNTIME140.dll and MSVCP140.dll Errors

Start with the safest, official methods. Always back up your system first.

1. Run System File Checker (SFC /scannow)

Windows' built-in tool scans and repairs corrupted system files automatically.

• Right-click Start > Search for "PowerShell" > Run as administrator.
• Type sfc /scannow and press Enter.
• Wait for the scan to complete – it will fix issues automatically.
• Restart your PC.

2. Reinstall Microsoft Visual C++ Redistributable (Recommended)

The most reliable fix: Download official packages from Microsoft.

• Visit the Microsoft Visual C++ Redistributable page.
• Download and install both x86 and x64 versions for your system.
• Restart and test.

3. Manually Replace the DLL File (Use Caution)

As a last resort, replace the file – but only from trusted sources to avoid malware.

• Determine your system: 64-bit DLLs go to C:\Windows\System32\; 32-bit to C:\Windows\SysWOW64\.
• Download matching version (32-bit or 64-bit) from official Microsoft sources.
• Extract and copy to the folder, overwriting if prompted (backup original first).
• Or place in the app's folder (e.g., for error 0xc000007b).

4. Reinstall the Affected Application

Uninstall via Settings > Apps, then reinstall from the official source.

For stubborn apps, use a tool like CCleaner: Tools > Uninstall.

5. Update Windows Drivers
