The error hits right as AION 2 tries to launch. A window pops up with code 0xE0000027, the game dies, and you’re back to staring at Steam. The cause is almost always a background service or overlay that NCSoft’s anti-cheat flags as interference. The fix is a clean boot of those services and killing every overlay in the chain. Here is the exact sequence that works.<\/p>\n
AION 2’s launcher and anti-cheat system are touchy about what else is running. When a non-Microsoft<\/a> service like a hardware utility or performance tool loads before the game, it can trip the error. You will see it most often after a fresh boot, because that is when startup services and scheduled tasks activate. The fix is to isolate what is conflicting, disable it, and relaunch.<\/p>\n The error code<\/a> itself points to a service-level conflict. AION 2 expects a clean environment. Process Lasso, ParkControl, and a scheduled task called “Empty Standby List” are known offenders. Overlays from Steam, Discord, Purple, and MSI Afterburner compound the problem. You do not need to uninstall anything. You need to<\/a> disable them temporarily, launch the game, and confirm the error is gone.<\/p>\n Open the Start menu, type Click “Disable all.” This turns off every third-party service that could conflict. Click Apply, then OK, and restart your PC. When Windows comes back, launch AION 2 through Steam or Purple. The error clears for most players at this step.<\/p>\n If the game launches, you can return to These two tools are frequent culprits. Process Lasso forces CPU core assignments and can interfere with the game’s thread management. ParkControl adjusts CPU core parking and creates the same issue. Both run in the background even when you are not looking at them.<\/p>\nStep 1: Disable All Non-Microsoft Services<\/h2>\n
msconfig<\/code>codecodecodecodecodecode, and hit Enter. Go to the Services tab. Check “Hide all Microsoft services” at the bottom. This is critical \u2014 Microsoft services are the backbone of Windows. Leave them alone.<\/p>\nmsconfig<\/code>codecodecodecodecodecode and re-enable services in batches. This tells you which one caused the conflict. Re-enable NVIDIA Display Container, for example, and test. Then re-enable AMD Ryzen<\/a> Master and test. You find the problem service without living in a permanently stripped-down system.<\/p>\nStep 2: End Process Lasso and ParkControl<\/h2>\n
