All right, try this:
- Uninstall Zurich, and reply "Yes" to the question about removing the Addon Manager.
- Reinstall and see if it works.
If not, try this:
Look in those places for the file esellerateengine.dll :
c:\Windows\esellerateengine.dll
c:\ProgramData\Esellerate\esellerateengine.dll (hidden folder, enable hidden folders view in Explorer to see it)
c:\yourFSXfolder\esellerateengine.dll
If you find any of these files, try deleting them all, and then relaunch FSX.
If you still have the unexpected quit, please contact via email.
