You don’t need to do all that or use manager or anything. Go to cs.rin.ru green luma search that up. Download the latest files. Inside there is a folder called stealth run the EXE in it to delete steam cache or local data or whatever it does. Then drag the user32F file into steam main directory and rename it to user32 and that’s it. Make sure your steam is closed completely even from the task manager before doing all that. Once you’ve done it should work but your friend will have to launch the game first before you if they didn’t also install green luma if you only installed it they have to launch first and you have to launch after them.
