Game Won’t Start Due to Missing DLL? Here’s What to Do (2025)

It’s a classic gamer nightmare: you double-click your favorite game, and nothing happens—except a “missing DLL” error. Here’s how to fix it, based on real-world experience.

Why Does This Happen?

  • The game needs a specific DLL file (like d3dx9_43.dll, vcruntime140.dll, etc.) that’s missing or corrupted.
  • This can happen after a Windows update, a new install, or moving games between PCs.

How to Fix It

1. Read the Error Message

  • Note the exact DLL file mentioned. This will guide your next steps.

2. Install the Required Runtime

  • For DirectX DLLs: install the latest DirectX End-User Runtime.
  • For VC++ DLLs: install the latest Visual C++ Redistributable (both x86 and x64).

3. Verify Game Files

  • Use your launcher’s “Verify Integrity” feature to restore missing files.

4. Use a Trusted Repair Tool

5. Avoid Unofficial DLL Download Sites

  • They’re risky and often unsafe.

6. Reinstall the Game

  • Sometimes, a clean reinstall is the fastest fix.

Quick Tips

  • Keep Windows and your drivers up to date.
  • Exclude game folders from system cleaners.

Most missing DLL errors are solved by installing the right runtime. Don’t panic—just follow the steps!
