A problem with antivirus is the most common cause for missing Add-on Manager or Couatl and GSX menus so, first try the following procedure:
- Go into Control Panel, Uninstall GSX and reply YES to the questions "Do you want to remove the Addon Manager ?" and reply YES to the question "Do you want to remove the Couatl script engine ?"
- TURN YOUR ANTIVIRUS OFF.
With the antivirus still disabled, reinstall GSX. Use the latest full GSX installer on our site.
- BEFORE launching FSX, configure the antivirus to exclude the following files from scanning:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\Couatl\Couatl.exe
- Now you can turn your Antivirus on, and launch FSX
- Note if FSX asks permission to run the Addon Manager and the Couatl programs, reply YES to both. PAY ATTENTION TO THIS.
- When FSX loads, check if you have BOTH the "Addon Manager" and the "Couatl powered products" under the "Addons" menu.
