Thank you for your reply,
The problem seems to be that the GOG installer crashes and no shortcuts are created.
I get the game folder installed in the playonlinux games folder, but there are only a .lnk file, which is binary it seems.
I have tried to run a global installed version of dosbox which works with a game such as theme hospital,
but not games like lands of lore 2 or wing commander 3.
If i try to run the local dosbox with conf arguments as suggested i get different errors:
Cannot open assembly 'DOSBOX/DOSBox.exe': File does not contain a valid CIL image.
or in other games a bunch of fixme messages before dosbox shuts down.
