OK, I had no FSDT or Cloud 9 scenery on my computer (Win 7 64 bit). I am trying to install several FSDT scenery in FS9 (taking advantage of the May sale) but get a crash to desktop when starting FS9. When removing the FSDT scenery, FS9 starts OK again.
I read threads in this forum suggesting that the present of an antivirus was the cause. Problem is, I don't have an antivirus on this computer (I do have the firewall on but I haven't seen this mentioned as a problem). Do I need to also turn off the firewall?
Thanks
