Check if you have BOTH the Addon Manager AND the Couatl menus inside P3D
If not, it's likely your antivirus has blocked one of both, so no scenery will be seen.
- DOWNLOAD AND INSTALL with the antivirus entirely OFF
- 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 the sim yet.
- Configure the antivirus to exclude the following files from scanning:
YourP3DFolder\bglmanx.dll
YourP3DFolder\fsdreamteam\Couatl\couatl.exe
- Now you can turn the antivirus back on, and launch P3D
- Check you are seeing BOTH the "Addon Manager" menu AND the "Couatl powered products" menu under the "Addons" menu.
