Have you got, the first time after Zurich was installed, the request to trust the Addon Manager, and the Couatl script engine ?
If not, something is blocking the programs, most likely the antivirus. Try to reinstall with the Antivirus entirely disabled, and before launching FSX, tell it to exclude the whole FSX folder, including subfolders. Or, if it doesn't give the option to exclude a whole folder with subfolders, exclude bglmanx.dll from in the FSX root folder, and exclude Couatl.exe in the FSX\fsdreamteam\Couatl folder.
