Seeing this error? If you are, it means 2XKO has spotted that your system is running on a Windows version it doesn’t vibe with. Think of it like trying to bring an outdated controller to the arena — the game just won’t let you in.
The good news? A quick system tune-up usually clears the way. Here’s how to fix it:
Check your Windows version
- Make sure you’re running a supported version of Windows for 2XKO
- If you’re not, update Windows to the latest version available
Try disabling compatibility mode
- On your desktop, right-click on your 2XKO.exe file
- Select Properties > Compatibility
- Disable Run this program in compatibility mode for...
- Click Apply > OK, then relaunch the game
Once that’s done, you should be cleared to re-enter the fight!
