Military AI Works

For some reason I'm getting FS9 detected when using AI-Aircraft Editor and ADE.

Checked the Windows 11 registry but couldn't find an entry for FS9. Using FSX and found that OK.

Any help wolud be appreciated.

TIA

The first place that I would look in your registry is :-
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Microsoft Games\Flight Simulator\9.0

If that node exists then delete the node and all the keys underneath it.
