[Solved] FlightIllusion not connecting to FSUIPC/MSFS 2024

skythelimit · 2025-12-30T21:59:04Z

Hi John Flightillusion (FI) gauges were working fine for me under MSFS 2020/FSUIPC7 v7.5.5. I didn't use the FI MSFS2020 sw, as you cannot customize anything with offsets and there were several gauges missing or not working. Unfortunately they are not in business anymore. So I used the penultimate version (v10.1.4) and all my gauges worked perfectly. Having just moved to MSFS 2024 and updated to FSUIPC beta 7.5.6b the FI sw no longer connects, see image below. Maybe you know if something changed between fsuipc 7.5.5 and 7.5.6b that may have caused this. I thought of our discussion hereand changed the entry to init3308=14 for MSFS 2024 but that doesn't seem to be it As another clue, I can only open the FI program if I select OPEN, running as administrator (which I akways did under MSFS 2020) comes up with the error in the 2nd pic below I hope you can help so I can get my gauges working again! Thanks! Charles

I think it is simpler if I just prevent further updates of offset 0x3308 if it is initialised using the init3308 ini parameter. You then don't need a lua script to keep this up to date. I have made this change in the attached version (7.5.6c) if you would like to try it.

Thanks very much John, I'll try that and take out the Lua scripts. I have left in the .ini

init3308=13

Hi John,

For me version 7.5.6c is working perfect (without the lua file) in MSFS2024 with 2020 drivers from Aivlasoft and Flight Illusion (both are out of business so no driver updates anymore).

Thanks,

Hans
