Thank you for your fast reply, also another problem (searched everyone noone else has this problem). I run game 1st time and it's ok. After I close the game and try again. dsetup.dll changes it's size (to approx 23kb) and then I can't run the game, to fix that, I need to replace dsetup.dll again.. and that happens everytime I close lineage2.
Additional info:
I have no antivirus or any windows guard enabled.
I have also reinstalled windows to Windows 7 (Had windows 10 and was the same thing happening).
I hope you get what problem I have.
Thanks.
