Why is in the lfsb-FSDT.ini the Path D:\LFSB\P3D_Files\Fsdreamteam\LFSB_ADEP4_MAX.bgl I think this is wrong.
No, it's not wrong. GSX manual, page 40:
The AFCAD pathname contained in the .INI file is not mandatory: if no file with that name is found in the full path, any other AFCAD matching the name only will be used instead, regardless of where it’s actually installed.
The reason why the full path is included in the .INI, is to serve as a DOCUMENTATION to the developer or whoever made the .INI file, to make it clear which was the ACAD HE based that .INI from but GSX will ignore it and will use just the filename, so that .INI will work everywhere.
