Last time I played SC2 was 3 weeks ago and it was working perfectly fine, but this week I get the “unexpected fatal error occured” message whenever I try to launch it. The error code is all 0s. Blizzard support gave me a generic response with links to the basic troubleshooting steps.
I have made 0 changes to my PC when it started happening. After that I’ve tried every possible solution I could find on the internet except for reinstalling Windows completely. But nothing worked for me and the issue persisted.
It’s a long shot but maybe someone here had the same issue recently and knows something that I don’t?
Here’s a list of what didn’t work for me:
- Starting the game as admin
- Starting the game in compatibility mode (Windows 7/Windows 8)
- Disabling the full screen optimizations
- Starting the game with extra parameters
- Resetting the ingame settings
- Running the 32-bit Client instead
- Switching the region
- Changing the ingame language
- Trying a different ISP
- Repairing the game
- Reinstalling the game and the launcher completely
- Installing the game to a different partition
- Removing every trace of Starcraft/Blizzard/Battle.net on my PC (including the folder in documents)
- Running every executable from the game folder
- Updating Windows
- Updating NVIDIA drivers
- Uninstalling OneDrive (it was never there to begin with)
- Disabling Windows firewall
- Booting Windows with every 3rd party application turned off in msconfig
StarCraft 1 and Heroes of the Storm work fine. I’m on Windows 10.
