Running into DirectX errors when launching games is a common issue for many Windows users—especially when playing graphics-intensive titles such as Call of Duty, PUBG, or GTA V.
Common error messages include: "DirectX function error", "Failed to initialize DirectX", or "d3dx9_42.dll is missing". These issues often prevent the game from launching or cause it to crash.
This article will analyze the most common causes of DirectX errors and provide a complete set of solutions to help you quickly restore your gaming experience.
1. What Is DirectX?
DirectX is a set of multimedia APIs developed by Microsoft for Windows platforms. It is widely used for graphics, sound, and game execution. Most PC games depend on DirectX, and if this component malfunctions, the game may fail to start or run properly.

In the Command Prompt, enter the following command and press Enter: sfc /scannow
Wait for the system to scan and repair any corrupted files.
Method 4: Install Microsoft Visual C++ Redistributable
Some games require Microsoft Visual C++ Redistributable in order to use DirectX features properly:
On the Microsoft website, search for "Microsoft Visual C++ Redistributable".
Choose the version that matches your system and click "Download".
After downloading, double-click the installer to complete installation.
Restart your PC and try launching the game again.
Method 5: Check for Windows Updates
Go to Settings > Update & Security > Windows Update.
Click "Check for updates" and install all available updates.
Restart your computer and test the game again.
DirectX errors are common, but most can be resolved by updating the DirectX runtime, graphics drivers, and related system components. If the issue persists, you may also try uninstalling and reinstalling the game.
