Good Evening, I am trying to load Euroaion through the launcher and unfortunately I am faced with the error Launch Error please close all games 3. I have looking all over the internet for an answer on how to fix this however not managed to find any answers. Has anyone ever had this issue? I see many had it for windows 10 but not a single post or forum that mentions having the issue with windows 11. Any help appreciaited. Thanks, Jonesy

Hey there,

Can't really say how Win 11 differs, but honestly, I think the problem might be something else than the OS itself. I know players using Win11 who can play just fine.
So I still suggest following this "guide" for the error and trying out these steps (as much as possible, of course).

a) Shutoff Third-party Apps at Startup:
Simultaneously press Windows & R -> Type in "msconfig" -> OK -> go to the Services tab and tick Hide All Microsoft Services checkbox at the bottom -> click on Disable All button.
Next, go to the Startup tab and press Open Task Manager -> select all 3rd party programs running and hit the Disable button -> OK.
b) Add the game to the whitelist in every antimalware (including regular Windows Defender) and firewalls
c) On Windows 10, turn off kernel isolation:
Use Search bar -> type "run" and open it -> type regedit -> OK
Find HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/DeviceGuard/Scenarios/HypervisorEnforcedCodeIntegrity and modify Enable from 1 to 0
Restart your PC

If fixing it this way doesn't solve the issue, then maybe a new Windows update is behind it.
Could be worth removing that update:

Settings -> Update and Security -> Windows Updates Center -> Update history

Remove the update from the screenshot below and any others from the same date (your date might differ).

By the way! If you're still facing issues, you might wanna consider looking at Aion Riftshade. It's launching Q1 2026 and their server is top-notch. I’ve been beta testing it, and it features a real MyAion-like integrated DPS Meter, server-side anticheat, and premium EU hosting with the lowest ping. Honestly, the best Aion private server 2026 could ask for, and definitely not P2W. Join the Aion Riftshade Discord for more insider info!
