Can you install 747-400X on FS9?

[cj-ibbotson 77]

Hi folks,I bought the excellent 747-400X for FSX a couple of months ago and love it but due to some stability issues in FSX which may be attributed to my system overclock I'm considering re-installing FS9. I will continue to try and iron out the overclocks which have only recently given me problems in FS and not limited to just the PMDG aircraft.Will the 747X work in FS9 with the latest FS9 patch or do you require the original Queen of the Skies for FS9 installer. If the later is the case will my license files etc from my 747X version work on FS9. I would hate to not be able to fly it in FS9 ;-(RegardsChris Ibbotson

No, it does not work in FS9. That's why there's two separate versions, the underlying code is very very different between FS9 and FSX addons and it wasn't possible for us to make a single version work with both.

Thanks Ryan,I did suspect that was the case but I recalled that the 400X installer had some function to update the FS9 version so thought I would enquire if they were compatible. I guess I will have to persevere on getting the system stableChris Ibbotson
