Fix Microsoft Visual C++ Runtime Error on Windows 10

Yes, the Microsoft Visual C++ Runtime error on Windows 10 can be solved by reinstalling the Visual C++ Redistributable packages, updating Windows, or repairing the affected application. This article walks you through the most common causes and step-by-step fixes, so you can get back to work without reinstalling your whole system.

What Causes the Visual C++ Runtime Error?

The error usually appears when a program that depends on the Visual C++ runtime libraries cannot find the required DLL files (like msvcp140.dll or vcruntime140.dll). These libraries are shared components that many Windows applications use. The problem often starts after a Windows update, a new software installation, or when an older program tries to use a newer version of the runtime than what is installed.

How the Visual C++ Runtime Works

Microsoft Visual C++ Redistributable packages install the runtime components needed to run applications developed with Visual C++. Each version (2015, 2017, 2019, 2022) has its own set of DLLs. Many programs install the version they need, but sometimes they overwrite or remove files that another program relies on. The runtime is not a single file – it is a collection of DLLs that must match the version the program was compiled against. When a mismatch occurs, Windows throws a runtime error.

Quick Fixes to Try First

Before diving into complex repairs, try these simple steps – they resolve a surprising number of cases:

• Restart your computer. A fresh boot clears temporary file locks.
• Run Windows Update and install all pending updates, then reboot again.
• Uninstall the program that triggers the error, then reinstall it with administrator rights (right-click the installer and select “Run as administrator”).
• Check if the error appears in a specific application only. If so, that app’s installer may have failed to install the runtime – reinstalling the app is often enough.

Reinstall the Visual C++ Redistributable Packages

If the quick fixes fail, the most reliable solution is to reinstall all Visual C++ Redistributable packages. Here’s how:

1. Open Control Panel → Programs and Features.
2. Look for entries like “Microsoft Visual C++ 2015-2022 Redistributable (x64)” or similar. You may see several versions.
3. Uninstall each one (both x86 and x64 versions). It is safe to remove them all – you will reinstall them right after.
4. Restart your PC.
5. Download the latest supported Visual C++ Redistributable packages from Microsoft’s official website. The download page offers both vc_redist.x64.exe and vc_redist.x86.exe.
6. Install both versions. Even if you have a 64-bit system, many programs still need the 32-bit (x86) runtime.
7. Restart again and test the application that gave the error.

Installing both x86 and x64 is critical – a common mistake is installing only the x64 package, leaving 32-bit programs without their required runtime.

Use System File Checker and DISM

Sometimes the runtime error is a symptom of corrupted system files. Windows includes built-in tools to repair them:

1. Open Command Prompt as administrator (type “cmd” in the Start menu, right-click, select “Run as administrator”).
2. Run sfc /scannow and wait for it to finish. It may take 10-15 minutes.
3. If errors are found, run DISM /Online /Cleanup-Image /RestoreHealth and then run sfc /scannow again.
4. Restart your PC and try the application again.

These tools check and repair Windows system files, including some runtime components. They do not affect your personal files.

Repair the Specific Application

If the error only happens with one program (like a game, an office suite, or a design tool), the problem may lie in that app’s installation. Most modern installers include a repair option:

• Go to Control Panel → Programs and Features.
• Find the program, select it, and click Change or Repair (the exact wording varies).
• Follow the on-screen instructions. This often reinstalls missing runtime files without removing your data.

If no repair option exists, uninstall the program completely, delete its leftover folder in Program Files or AppData if any, and reinstall from the original installer.

Advanced: Check for Malware and Clean Boot

In rare cases, malware can block or replace runtime DLLs. Run a full scan with Windows Defender or your preferred antivirus. Also, a clean boot helps identify if a background service is interfering:

1. Press Win + R, type msconfig, and press Enter.
2. Go to the Services tab, check “Hide all Microsoft services”, then click “Disable all”.
3. Go to the Startup tab and click “Open Task Manager”. Disable all startup items.
4. Restart. If the error disappears, re-enable services and startup items one by one until you find the culprit.

Remember to re-enable everything after testing – a clean boot is a diagnostic tool, not a permanent state.

Frequently Asked Questions

Why does the error say “runtime error” even though I just installed the latest Visual C++?

Simply having the latest version does not guarantee compatibility. Some programs require an older version (like 2013 or 2010) that the newer redistributable does not include. Install all available versions from Microsoft’s official site – they coexist peacefully.

Is it safe to uninstall all Visual C++ redistributables?

Yes, it is safe to uninstall them, but only if you reinstall them immediately. Removing them without reinstalling will cause many programs to fail. Always download the latest from Microsoft’s official page.

Will reinstalling Visual C++ affect my personal files?

No. The runtime packages only install system DLLs and registry entries. They do not touch your documents, photos, or other user data.

What if the error persists after all these steps?

If you have tried reinstalling the runtime, repairing the application, and running SFC/DISM, the issue may be deeper – perhaps a corrupted Windows installation or a failing hard drive. Consider performing a Windows 10 repair install (keep files and apps) or consult a professional.

Can I just copy the missing DLL file from another computer?

It is not recommended. DLL files are version-specific and may not match your system architecture. Copying them manually often causes more errors. Always use the official installer.

Does this error happen on Windows 11 too?

Yes, the same runtime error can occur on Windows 11. The fixes are identical – the steps above work on both operating systems.
