HI JF Godel,
Thank you for the more details about the Simlink installation.
From the screenshot, it looks like there is some wrong with your FSX flight Simulator.
Simlink detects two versions of FSX. So if you are using the Steam version of FSX then there are some old FSX version garbage registry exist in your Windows OS.
But we can correct the Simlink settings for Flight Simulator.
Can you please clean up the Simlink configuration by this? After the clean up please reinstall Simlink Plugins.
Please feel free to inform us.
Kind Regards,
Vishal Ahir
