Its a kernel based anti cheat system. Fex Delta Force uses it. If it doesnt shut down the process after leaving a game that uses it just a simple restart of the pc usually solves that for me.

If you had a game previously that used the ACE anti cheat and unistalled the game it often leaves behind "traces" that you manually have to remove.

this site has a guide for it:

I did everything I even uninstalled the ACE-BASE files, it still doesn't work for me, I followed the guide step by step, do you have any other ideas?

same problem since installing deltaforce

Hey guys - I had this same issue today and coincidentally, I had played delta force today as well.

What I did was: Re-open delta force> select warfare gamemode> press esc> exit game

Due to delta force being kinda new and still buggy, I think if you "ALT/F4" to close delta force it wont close properly, thus leading to errors like this.

After doing what I did, Rust started just fine, no editing of files or restart needed.
