I apologize if this topic has been discussed in the past, but I can't find anything useful.
When i try to install GSX, or the addon manager, after the screen asking me if I want or not download the latest cads for fsx, the setup program goes directly to "installation complete" window (YES or NO, it's the same).
It seems the installation gone ok, but in FSX nothing change, there's no addon manager or GSX anywhere.
I have the FSX SE, correctly detected by the setups, and I purchased GSX two days ago.
Thank you for your help.
