Hello
1-Windows Security, Antivirus programs, Riot Vanguard and FaceIT Anticheat software block our cheats. you should disable or uninstall these programs.
2- Install the programs from the links I gave you below
2.1-
2.2-
(Unzip it to the folder, then run the install_all.bat script as administrator.)
3- Sometimes there is a crashing problem due to the config, try deleting the LPRB in %appdata% and entering the Training Mode
You can try to play in full screen with 4-window (tick the Prefer old OpenGL mode option from the graphics section of the in-game settings, switch the game to full-screen windowed and try again.)
5- Do not sub-tab and press any key while injecting the cheat, if the problem persists, you can contact me without private conversation.
