Not sure this will help you, but maybe you get lucky.
I recently had a similar problem where after a complete reinstall of FSX:SE most of my addon installers where not able to detect that FSX was installed and always asked me to point them to the FSX directory.
After some trial and error I found out that the problem was a missing .cfg file in the .../AppData/FSX Folder (I don't recall the exact path). that .cfg file gets automatically created when you start FSX for the first time via the fsx.exe. But i never did that after the reinstall, i always used the FlyInside.exe to start the simulator. And for some reason that I can't explain that .cfg file gets not created (or at least not at that location) if you start it via the FlyInside.exe.
long story short, maybe this applies to you? have you started FSX via the fsx.exe at least once? maybe after that FlyInside will be able to find the path to the fsx.exe, too?
