Ok noticed the following on my system...
After a GSX install no GSX ICON and couatl not started... (even after a live update or manual install of the *dat file...)
Old timer here regarding Flightsim and GSX so an uninstall of all FSDT stuff and removing the addon manager folder and a reinstall solved that one.
Only noticed that couatl isn't added to the exe.xml file no entry so I have to start that one manual!
Umberto do you have the correct XML entry so I can add it manual?
GSX cfg file via the installer works fine also to exclude all the 3d party add-on stuff in one run...
Off to explore version 3.0
