Hi, yes, I do take backups of my entire PC every week to an external drive, just as well that I do.
I now have 2 ADDON MANAGER folders inside my GSX folder, a PRE update folder (recovered from a backup), and a POST update folder, I obviously need to jig the folder names so that only one is active at any one time.
With the help of many other posters, renaming/removing/inhibiting INI files in the scenery folders and inside the VIRTUALI folder, and adding PARKINGSYSTEM = 0 to ALL the parking gates in airports that did not work post update, and the gentleman who gave the files to get SODE working at UK2000 Heathrow.
I can now flip between PRE update and POST update at will in a few seconds.
Now both PRE and POST UPDATE work correctly (as far as I am aware !!) for me, but it has been a struggle and many hours spent trying various fixes.
I will wait a while before getting GSX for MSFS. That is just a step too far at the moment !!!!!!!
I will gladly help anyone that needs a solution if I can.
