Thank you for your help but this update not run
There hasn't been any update to the GSX setup. I haven't told you to download the installer, I only said to run it again, so it could get the online updates.
I download it and when I tried run the exe file I receive a message : GSX_FSx_setup.exe are not win valid ...
That's not a problem of the installer, but the file has been corrupted on your system. Such message seems to indicate your antivirus is at fault, that has corrupted the setup executable, mistakenly thinking it might contains a virus, and corrupting it trying to "heal" it.
Download the GSX installer again, with the antivirus turned off entirely, and keep it off while installing and before launching FSX, configure the antivirus to exclude the following files from scanning:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\Couatl\couatl.exe
YourFSXFolder it's usually C:\Program Files\Microsoft Games\Microsoft Flight Simulator X, if you installed it in the default folder.
- Now you can turn the antivirus back on, and launch FSX.
