Some Users have reported they also need to disable Estimate passengers number.
Fenix2GSX relies on GSX to open and close the Doors.If you want to keep your customized Config for whatever Reason, make sure the Option "Show MSFS Fuel and Cargo during refueling" is disabled! Make sure you do not have a customized Aircraft Config (GSX In-Game Menu -> Customize Aircraft -> should show only "Internal GSX Database").There is no Pop-Up and there will never be. The Program will display a little Exclamation Mark on the SysTray/Notification Area Icon and in the GUI to inform on a new Version. It may be blocked by Windows Security or your AV-Scanner, try if unblocking and/or setting an Exception helps (for the whole Fenix2GSX Folder).The Installer does not create a Backup (not deemed neccessary), so if you want a Backup, do so yourself. For Auto-Start either your FSUIPC7.ini or EXE.xml (MSFS) is modified.The Installation-Location is fixed to %appdata%\Fenix2GSX (your Users AppData\Roaming Folder) and can not be changed.From Version 0.4.0 onwards, your Configuration is not be resetted after Updating.If you upgrade from Version 0.3.6 or below, delete your old Installation manually (it is no longer needed).If the MobiFlight Module is not installed or outdated, MSFS also has to be stopped.Fenix2GSX has to be stopped before installing.It even setups Auto-Start and creates a Link on the Desktop, if you want.
Basically: Just run the Installer - it will extract it for you to a fixed Location and will also install/update the neccessary Software to your PC/Sim.
