Fix Assassin’s Creed Valhalla Not Launching on Windows 11
So, what could be coming in the way of the Assassin’s Creed Valhalla, preventing the action role-playing game from launching? From what I have experienced, things like corrupted game files, malicious drivers, and incompatibility are some of the biggest hurdles.
- Outdated drivers
- Corrupted game files
- Antivirus interference
- Insufficient system resources
- Incompatible software
- Windows updates missing
- Background app conflicts
- Overclocking instability
1. Check System Requirements
First and foremost, make sure to check your system requirements. Bear in mind that if your system doesn’t meet the minimum requirements, the game won’t launch or might crash on startup.
- Hence, ensure that your PC meets these minimum specs:
- Processor: Intel Core i5-4460 or AMD Ryzen 3 1200
- RAM: 8 GB or higher
- Graphics Card: NVIDIA GTX 960 or AMD R9 380
- Storage: At least 60 GB free space

2. Run the Game as Administrator
Be warned that the game might not have the needed permissions to access essential system files on your Windows device, causing launch issues. Hence, there is a decent chance that running it as an administrator may resolve the issue.
- To get it done, right-click the Assassin’s Creed Valhalla shortcut
- Now, select Properties > Compatibility
- Check Run this program as an administrator
- In the end, do not forget to click Apply > OK
3. Update Graphics Drivers
It’s no secret that outdated or corrupted graphics drivers can prevent the game from launching properly, as they may not support the latest game updates or DirectX features. Therefore, make sure to update your graphics drivers since they might be spoiling your game.
- To do so, press Win + X and select Device Manager.
- Expand Display Adapters, right-click your graphics card, and choose Update driver.

- Select Search automatically for updated driver software.

5. Update Your PC
Keep in mind that the outdated Windows versions may lack important updates, such as security patches or drivers, which might be pivotal for the game to run correctly.

Unnecessary background processes can consume CPU, RAM, and GPU resources, causing the game to fail to launch due to insufficient resources.

7. Disable Antivirus and Firewall Temporarily
It’s also worth reiterating that your antivirus programs or firewall settings might be blocking Assassin’s Creed Valhalla’s executable file, preventing it from launching. Temporarily disabling them helps rule out this possibility.
- Press Win + I to fire up the Settings app > Privacy & Security > Windows Security > Virus & Threat Protection.

- After that, turn off real-time protection
- Disable the firewall under Firewall & Network Protection
8. Run Valhalla in Compatibility Mode
Sometimes, games designed for older versions of Windows may not run smoothly on Windows 11. Compatibility mode helps by simulating an older Windows environment.
- Right-click the game’s shortcut and select Properties
- Go to the Compatibility tab and check Run this program in compatibility mode

9. Install DirectX and Visual C++ Redistributables
Assassin’s Creed Valhalla relies on DirectX and Visual C++ Redistributables to handle graphics and runtime libraries. Missing or outdated versions can cause launch issues.

- Install both and restart your PC
10. Check for Game Updates
Game updates often include bug fixes and performance improvements that may resolve the launch issue.
