For some reason PF3 believes you are using FS2002
6/14/2021 1:39:52 PM: 210 - PF3 Version: 3.10.50
6/14/2021 1:39:52 PM: 210 - FS Version: FS2002
6/14/2021 1:39:52 PM: 210 - FSUIPC Version: 3.999Z
Here's my log for FS9
16/06/2021 16:35:07: 140 - PF3 Version: 3.10.57
16/06/2021 16:35:07: 140 - FS Version: FS2004
16/06/2021 16:35:07: 140 - FSUIPC Version: 3.999Z
I can't explain why this is happening. PF3 simply reads the info from FSUIPC and I see you are using the correct version of fsuipc. I use FS9 all the time whilst testing and coding as it loads so much faster than MSFS so I know there's no issue with it. What version of FS9 do you have installed (right-click on FS9.exe and select 'Properties/Details')?
Mine is File Version 9.0.0.30612 and Product Version 9.00.030612.02
