How to Fix Dev Error 5759
Try the following solutions in the order presented. They are known to be effective for many players.
1. Update Your Graphics Drivers
Outdated drivers are a primary cause of Dev Error 5759. Whether you’re using NVIDIA or AMD, head to their official websites and download the latest drivers for your GPU. Avoid using Windows Device Manager for this task as it may not fetch the most recent drivers.
Steps:
- Visit the NVIDIA Driver Download page or AMD Support.
- Enter your GPU specs and download the latest stable driver.
- Use Clean Installation during the driver setup to remove older versions completely.
2. Verify Game Files
Corrupted or missing game files can cause runtime errors. Verifying your game files through Battle.net or Steam can resolve this issue:
- On Battle.net: Go to your game > Click the gear icon > Select Scan and Repair.
- On Steam: Right-click the game in your Library > Go to Properties > Local Files tab > Click Verify Integrity of Game Files.
3. Reinstall or Restore DirectX
Dev Error 5759 can stem from issues with DirectX components. Install or restore the latest version:
- Download the latest DirectX End-User Runtime from the Microsoft website.
