Are you seeing the error “DirectX function ‘CoInitialize()’ failed with HR” when launching or playing games like Battlefield 6, Call of Duty, or other DirectX 12 titles on your AMD GPU system?
This frustrating error usually appears with a message like:
“DirectX function ‘CoInitialize()’ failed with HRESULT 0x800401F0”
Description: “CoInitialize has not been called.”
This error often occurs before the game fully loads or after changing graphics settings. It’s linked to DirectX initialization failure, most commonly triggered by driver conflicts, corrupted system files, or registry issues — especially with AMD Radeon setups.
Why This Happens (Technical Breakdown)
The CoInitialize() function is a Windows COM (Component Object Model) call that prepares your system for graphics rendering tasks using DirectX. If this call fails:
- The game can’t initialize DirectX features
- Rendering context can’t be created
- The engine exits or crashes with an error
This usually means:
- DirectX files are corrupted or missing
- Faulty or outdated AMD GPU drivers
- A third-party overlay or program is interfering
- Corrupt Windows system/registry files
- Incompatible AMD Adrenalin settings or features
How to Fix “CoInitialize() Failed with HR” on AMD GPUs
1. Reinstall DirectX Completely
Even on Windows 11, older DirectX components can become corrupted.
Steps:
- Download the DirectX End-User Runtime Web Installer from Microsoft:
👉 https://www.microsoft.com/en-us/download/details.aspx?id=35 - Install and restart your PC
- Try launching the game again
2. Do a Clean Install of Your AMD GPU Drivers
Faulty drivers are one of the most common causes of this error on Radeon systems.
Step-by-step:
- Use Display Driver Uninstaller (DDU):
- Download from here: https://www.guru3d.com/download/display-driver-uninstaller-download/
- Run in Safe Mode to fully remove AMD drivers
- Download and install the latest WHQL AMD drivers:
👉 https://www.amd.com/en/support - Use the “Factory Reset” option during install if available
- Reboot and test the game
Avoid using “Optional” (beta) drivers unless you’re testing a specific fix.
