i installed IWD II (GOG-Version) with the install-script from here succesfully. Then i istalled libpng12-0_1.2.54 (https://packages.ubuntu.com/xenial/amd64/libpng12-0/download) and libsdl-image1.2 manually, but the game doesn’t start.
Also make sure “Disable Lutris Runtime” under System options is not checked.
Hej, sorry for that.
Lutris Runtime was disabled.
So it’s solved?
