Btw the Addon manager was not even appearing from my add ons in FSX
Have you followed these two steps ?
- 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 ?"
- Note if FSX asks permission to run the Addon Manager and the Couatl programs, reply YES to both. PAY ATTENTION TO THIS.
