Shouldn't we look for both Fallout3Launcher.exe and FalloutLauncherSteam.exe as most people downgrade to 1.7.0.3 for mod compatibility or does the new launcher work with 1.7.0.3?

The new launcher works with 1.7.0.3 and downgrading using the patcher from nexus mods only modifies fallout3.exe, it doesn’t touch the launcher.

On my system this script refuses constantly to work. Here all commands I tried. The Steam-Libary on my 2. SSD was created with a local installation of the Steam-Client on my debianbased MX-Linux 23.3. I cannot be that one is forced to install the games in the standard-libary of Linux and that it is forbidden to install it elsewhere e.g. on a second drive, due to my plans of a vast modding.

So can anybody help, please?
By the way, All prerequisites like protontricks, zenity, and so on are met.

Should fallout3.sh be similarly patched? I don’t own the non GOTY original release (appID 22300) so cannot confirm, but it also recently received a launcher update.

FalloutLauncherSteam.exe does not exist and causes errors upon installation. I updated the game_executable to be the correct "Fallout3Launcher.exe" and was able to install MO2 without issue

Was so confused why this was working for vegas but not 3 goty, changed the text and I'm unblocked! Thank you :^)
