@Premek I have a solution for at least LSZH and LKPR. Both Airports are working. How long has it now taken to find the bug? One year?   1. Install LKPR (Backup APC Folder) 2. Deinstall LKPR 3. Install LSZH (Backup APC Folder) 4. Install LKPR 5. Copy back the Content of the backuped  LKPR APC Folder 6. Check the entries of APC.cfg with the backup APC.cfg's (the system is similar to  exe.xml/dll.xml  -- I attached my working file) 7. Add the Jetway Patch
