Opening the gmapsupp.img file from Talkytoaster in QLandKarteGT won’t work.
Instead, you need to download one of the “Mapsource” versions from Talkytoaster. It should contain multiple img files (the map tiles), plus the tdb file etc. So you should be able to open that with QLandKarteGT. Just ignore the install.bat file, which is designed for use with MapSource on Windows.
