Launch Error After Update in Steam for Lost Ark

Game Support English Support
1

Been playing the game without issues until now, I closed my game client and steam required a small update for “Lost Ark”, and now I get the following error repeatedly: "Launch Error: Failed to start the game (2).

The issue started after the update, and it is happening to 2 other players I know of, and they had been playing without issues before the update.

Troubleshooting and checking file integrity did nothing.

I have the same issue. tried many things but nothing worked yet.

  • Repair EAC
  • Uninstall and Re-Install EAC
  • Repair game files via steam
  • Disabled all apps
  • Disabled Antivirus

Nothing worked

Me and one other friend have the same issue. It was related to my Anti-Virus (in both of our cases Webroot Antivirus) and I had to completely un-install it to be able to launch the game (disabling doesn’t work as webroot has some deep services running).

Looks like the recent update today caused a conflict with Webroot and possibly other antivirus.

LoL, im using webroot as well

yea this happened recently with Back 4 Blood as well. There’s some issue between Easy Anti Cheat and Webroot. They don’t play nice.

Exact same thing and I also have Webroot Antivirus

Hopefully smilegate/amazon look into this as id like to re-install my anti-virus. I really like webroot =(

Hey guys. You do not have to uninstall/disable WR for this to work. Just open Secure Anywhere and go to PC Security settings cog. In the Block/Allow files tab, click on Add File on the bottom. Navigate to where your game is saved e.g. C:\Program Files (x86)\Steam Library\steamapps\common\Lost Ark\Binaries\Win64

Once in that path, add the file Launch_Game (this is Easy Anti Cheat). Then click on Add File again from WR and add LOSTARK from the same file path. This will whitelist EAC and the game. Mine launched after this.

Getting the exact same issue.
“Launch Error Failed to start the game(2)”
I have done;

  • Reboot PC
  • Reboot Steam, update steam
  • Update game
  • Check intergerty of the game files
  • Whitelisted the game with my antivirus
  • Spoke with AGS support who basically said post about it here.
  • Forgot to include that I have tried to see if it was my steam account flagged, but the other game that runs EAC boots up fine…
