Same issue, and I only have the "Addon Manager" and NOT the "Couatl powered products" menu options, what does this mean?
That Couatl hasn't started. Since the libraries required by it are the same as the one required by the Addon Manager ( Simconnect FSX/SP2 and VC++ 2013 runtimes ), a problem with your system libraries might be excluded.
It goes back to the most common cause, of the antivirus blocking it.
- Uninstall the scenery. Reply YES when asked if you want to remove the Addon Manager and the Couatl Engine. Reply YES to both questions.
- TURN OFF your antivirus. Don't just exit from its interface, but turn off the real time protection. Actual wording changes between products, however, it's the option to scan every file that gets open in real time, without user intervention.
- Reinstall the scenery with the Antivirus TURNED OFF. Don't launch FSX yet.
- 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\steam\steamapps\common\FSX
- Now you can turn the antivirus back on, and launch FSX.
- Check you are seeing BOTH the "Addon Manager" menu AND the "Couatl powered products" menu under the "Addons" menu
