Please advice me how to do a proper and working installation of your product GSX
Just install the latest installer, that's it. Of all users (and there were so many of them), who contacted me to have a Teamviewer session, that were all convinced their problem was caused or started with GSX, the ONLY real problem I could trace back to the GSX installer, was the issue of slow loading under FSX:SE and with OrbX sceneries installed, and that's it.
All other issues were always caused by something else entirely. The most common case was FSUIPC not fully supporting the latest P3D Hotfix, several usual antivirus issue, several problems with outdated Ezdok camera. Some users just got unlucky, and got a corrupted download of some files, because the server was too crowded for a few days.
But I don't think you'll have any issues now, since everything reported has been fixed, and the server seems to work normally now.
And, we are updating to a new server, based on Amazon cloud services, so it won't happen again.
