By and large, scenery is handled in exactly the same way as it was in FS9 but with the advantage that you can add and delete it 'on the fly' as you could with 2002 and before. Unless there is something specific in the install instructions, continue to do as you did in FS9 One problem not directly connected could be the OS you're using.. especially where auto-installers are used. Thankfully, I'm still on WinXP so I can't offer any advice for the newer OS's
The file structure in your shot looks ok. Don't forget to go and manually activate the scenery in the sim (add new scenery/addon scenery/click on the folder to be activated)
Okay, Dave, thats the first part. But I can't activate Duxford in the the scenery library in FSX
In the picture above, when I select the folder EGSU Duxford and click OK...I get the picture below
I can never get past this, and am never returned to the scenery library. There is a thread on the OrbX forums to the effect that in Windows 7, if you click on the white area where the folders are in the first picture, you are dumped back to the scenery library screen where everything is at it should be...but that doesn't work for me.
