I get these errors when I launch the game through the Gaijin.net updater, the app running at start.
When I create a link to aces.exe on my desktop, and give it admin rights, the game launches with Easy anticheat instead, and then I can launch the game.
That’s why I started with verify integrity.
If you have Steam that’s done through game properties.
You can start manual launcher and verify game files there as well.
I did both file checks and even deleted and re-installed the entire game and still have this issue. I can manually launch the game from the exe/launcher but the battleye version through steam fails to run every time.
