He hecho directamente la consulta a John Dowson, quién inmediatamente me ha contestado ..... a continuación transcribo su respuesta.
He aplicado lo que me indica y el problema ya está perfectamente resuelto.
Su respuesta :
The two icons that the FSUIPC installer installs on your desktop only start MSFS2020 and MSFS2024 only (unless using the batch auto-start method, which you aren't).
When each MSFS version starts, does FSUIPC7 also auto-start? If not, then auto-start is not working.
[Programs]
runif1=READY,CLOSE,"H:\08 - Andalusi\Andalusi.exe"
runif2=READY,CLOSE,"H:\Little Navmap\Little Navconnect\littlenavconnect.exe"
Note that with the READY, the programs will not be started until an aircraft is loaded and ready to fly. If you want them started earlier, when MSFS is still in the menu system, use the keyword CONNECTED instead.
