Hi everyone I have recently started modding GTA IV, and needed dotnet48 to work for some mods.but as many of you may know current proton(4.11<) doesn't allow dotnet48 download. I scoured the internet and have found a work around. Originally posted on reddit

But I've condensed it to be easier to follow and decided to post here because I'm sure there are many reasons to need it for proton

Make a copy of the original ../gameid as a backup

use command: cp -RLv steam-path/gameid/pfx/drive_c/windows steam-path/gameid/pfx/drive_c/windows.dereferenced

remove steam-path/gameid/pfx/drive_c/windows

use command: mv steam-path/gameid/pfx/drive_c/windows.dereferenced steam-path/gameid/pfx/drive_c/windows

use command: protontricks appid -q -f dotnet48

use command: protontricks --gui

winecfg - change W7 to W10

Edit: the only thing that would be annoying about this I found so far is the pfx folder size goes from like 300mb to 1.6gb
