@The_Keeper86 I am testing this out right now and I had the same results as you with it continually asking to install dotnet. What I did was copy over all the directories (except for the data and media folders) from my existing Windows installation of LaunchBox to the Launchbox installation directory that was created from Lutris. Launchbox starts up now remotely on my SMB share when using GE-Proton7-43-x86_64.
