I have installed it like any other WINE app, but unlike all other WINE apps, it won't launch from WineExplorer.

From terminal it reports:
00e8:err:module:import_dll Library mfc140u.dll (which is needed by L"C:\\GOG Games\\Foundation\\foundation.exe") not found
00e8:err:module:LdrInitializeThunk Importing dlls for L"C:\\GOG Games\\Foundation\\foundation.exe" failed, status c0000135

mfc140u.dll is avaulable vie WINE Config, under vcrun2019 and related, but it doen't install properly for me - possibly due to a Wine Bug


EDIT: Got it working by downloading mfc140u.dll and placing it in the same folder as the launcher. Runs very nicely now.
