Hello Muhammed, sorry for the late reply. Did you perhaps choose the FSX installer instead of the -SE installer? You seem to have a separate hard drive for -SE, which would seem prudent. Yet, if the wrong installer was chosen, would you still be able to install? Maybe, maybe not. Ill effects would occur for sure if so. At any rate, have you attempted to uninstall FsP-SE, ensure no other FsP folders are still in the directory, reboot pc and re-install FsP? Please re-boot pc after another install.

The install log indicated Windows 8.1. I am uncertain of the last update Dan completed with FsP and Windows...especially with -SE. It seemed every time Steam would update FSX, something would break FsP. Perhaps this is one of those times...where you have 8.1 but -SE has a later version that Dan did not provide an update to FsP. If this latter is the case, I have no solution. Only the developer will have one if he chooses to engage.

never mind sir.
I got it from Fitgirl, not from the original site, but it's a steam version.
Yes, I deleted and reinstalled it and i did same for fsp, and moved it completely form ‪C:\Program Files (x86) to another file, but it did not work. I also looked at the solutions of other members and it did not work.
Is it possible to downgrade the version to solve the problem?

Are you saying that you got a copy of FsP-SE from another user?
