[Solved]FSX not starting - deleted reply?

[Fabrice]

So... I noticed that if I delete the FSX folder inD:\Users\My Profile\AppData\Roaming and re-launch FSX, it works (without FsP, as it does not detect
that it's installed). So I thought that maybe my profile was not cleaned enough last time I uninstalled. I uninstalled everything and re-installed
everything (this took two hours). FsP now works, but I have to configure everything correctly now to obtain the best FPS. But at least, it works...

Hope this can give a clue to those who experienced the same in the two topics I found and where no solution was given...
