Hi, can you check if you have the library qt5pas installed?

[compilenix]

Yes: qt5pas-2.6-2000804.fc32.x86_64

[shusaura85]

Unfortunately my only Linux installation at the moment is Ubuntu (the one used for the pre-compiled binaries) and I currently don't have time to work on it, and won't have time for at least 2 more months.
It might be faster for you to try and compile it from source using Lazarus IDE (and Free Pascal Compiler) as that is probably all it needs to work (just open the lazarus project and hit compile, nothing else needed).

Okay thanks :)

Other question, does notparadoxlauncher "simply" is and ui + settings and then forks the game with the defined arguments, or is there more to it?

[shusaura85]

Yup. It simply starts the game with the parameters set up in the options.
The launcher (and boostrapper) was designed to replicate the actions that Paradox Launcher does.
When Steam starts the game, it starts it with the dowser(.exe) binary. That binary then looks for the launcherpath file created by Paradox Launcher (and taken over by NPL) to see where the launcher is installed, then calls the boostrapper_v2(.exe) binary in the specified location. Bootstrapper then starts the actual launcher (official bootstrapper would do a launcher update, then start the latest version). The launcher in the end starts the actual game.
You can see the actual code in the launcher is simply starting a new process for the game with the specified configuration

Nice, thanks for the detailed description!
