Nice! I can implement a way to kill the application at some point. Are there any trigger we can use for this purpose? Like, is the login in a different process/executable, so I can stop it when came alive?

I don't think so. RiotClientServices.exe handles both login and download. After login a new process will open, but at that point, if the user did not close the launcher after downloading, the installation is broken. It is also problematic that you can log in while downloading!

Taking a look at the Lutris installer, they warn you before the installation starts. I think I can do that with a script, but I really don't wanna.

I can implement a native way to show a dialog. Looks like the only solution rn.

Which parameters are settleable? It seems the runtime cannot be chosen from the installer, neither if gamescope is enabled.

I've gotten league working, but I was able to walk through the install process start to finish, and the game has even been updated through the Riot Client and it still runs well. I used lutris-ge-lol-7.14-1by adding it with Protonup-qt.

@noey-drew Did you use the script in the PR?

I wouldn't say its dead but stalled. It would require having a message dialog to warn users not to login while the first installation of the game.

Also I don't know if there is other way to set some settings like the DLL overrides via Bottles config settings instead of with ENV variables
