Solving the 0xc000009a Application Error

If you’re encountering a problem where some of the games you play abruptly crash with the error message “The application was unable to start correctly (0xc000009a)” and a mention of a blocked opengl32.dll file, here’s how to troubleshoot and resolve this issue:

Solution 1: Update Graphics Drivers

Ensure that your graphics drivers are up to date. Outdated or incompatible graphics drivers can lead to OpenGL-related errors. Visit your graphics card manufacturer’s website to download and install the latest drivers for your specific GPU model.

Solution 2: Check for Windows Updates

Make sure your Windows operating system is fully updated. Some system updates include patches that address compatibility issues with games and graphics libraries like OpenGL.

Solution 3: Verify Game Files

If you’re experiencing this issue in multiple games, it’s a good idea to verify the game files. Most game platforms, such as Steam or Epic Games, have built-in tools for this. They’ll check and repair any corrupted or missing game files.

Solution 4: Disable or Uninstall Overlays

Game overlays from applications like Discord or GeForce Experience can sometimes conflict with games and cause errors. Try disabling or uninstalling these overlays to see if it resolves the issue.

Solution 5: Run as Administrator

Right-click on the game’s shortcut or executable file and choose “Run as administrator.” This can help with permissions issues that might be causing the error.

Solution 6: Check Antivirus/Firewall Settings

Your antivirus or firewall might be blocking the game from accessing the opengl32.dll file. Review your security software’s settings and ensure the game is allowed.

Solution 7: Install Microsoft Visual C++ Redistributable

Some games rely on specific Microsoft Visual C++ Redistributable packages. Make sure you have the required versions installed. You can download them from the official Microsoft website.

Solution 8: Repair or Reinstall DirectX

DirectX is closely related to graphics functions in Windows. You can repair or reinstall it to ensure it’s functioning correctly.

Solution 9: Consider System Restore

If the issue started after a recent software installation or update, you can perform a System Restore to revert your system to a point where it was functioning correctly.

Solution 10: Seek Technical Support

If none of the above solutions work, consider reaching out to the game’s official technical support or community forums for assistance. They may have specific solutions for the game you’re experiencing issues with.

By following these steps, you can troubleshoot and hopefully resolve the opengl32.dll error that’s causing your games to crash. It’s essential to ensure that your graphics drivers, Windows, and game files are in good order to enjoy a smooth gaming experience.
