Thanks for that configurator link. It worked. You save file as different name then overwrite config because FSX config folder is protected and you need to do some manual saving there.
I have FSX: Steam Edition. I have multiple addons and that internal game addon manager is crappy.
Question: How to add those addons without game addon manager tool? I have over 30 addons to add.
Also I still fly FS9 or FS2004 because it is SO good game.
