Hello.

 

 

 

When logged in, it showed Error EOS_session_invitefailed.

 

 

 

I tried to

 

1. Reinstall Ragnarok, and it showed CEasyAntiCheatGameLauncherMgr::CreatInstance() when launching the game.

 

2. I followed CM Poring guide to remove EAC and re-patch, but it did not work.  https://forums.warpp...to-launch-game/

 

3. I tried to click Easy AntiCheat in C:\Program Files (x86)\EasyAntiCheat_EOS and C:\Gravity\Ragnarok Online\EasyAntiCheat but nothing happened (it disappeared).

 

4. I tried to install it on another PC, and it did not work.

 

 

 

This happened after they updated the EAC last week.

1 - Make sure you have Win10/11 x64 version, x86 versions are mostly unsupported
2 - Go to your Ragnarok Online/EasyAntiCheat route and make a shortcut for EasyAntiCheat_Setup.exe, put this in the command line: qa-factory-reset
3 - Execute the shortcut and this should have closed the EAC service if started in the first place + clean the registry keys
4 - Go to your Registry Editor in Windows and check if you have HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\EasyAntiCheat_EOS. If you do then delete the folder
5 - Delete your entire Ragnarok folder and download the full client from here https://mirror.irowi...Feb-13-2025.zip
6 - Once downloaded and extracted run the Ragnarok.exe and wait for it to update
7 - Run Updater.exe (it does nothing visible but still do it)
8 - Check if HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\EasyAntiCheat_EOS exists, it should exists
9 - Open the game through the launcher as usual

Sometimes an outdated version of GPU drivers can interfere with anti-cheat. Make sure your NVIDIA or AMD drivers are up to date.
