Gentlmen,What does Unify mean of the PMDG747_400_V1R12_FSXFS9_Unifier.exe?Would you please instruct me?Sincerely,Kan-ichiro Fushihara

That's the FS9 747-400 Update. Unifier basically means it unifies certain 747X features with the FS9 version. But if you're already using the 747X, you really don't need this.Ryan GamurotLucky to live Hawai'ihttp://www.virtualpilots.org/signatures/vpa296.png

Thanks Ryan,I understand.The unified PMDG 747-400 FS9 is cannot start on my machines both of XP and Vista. It has forced restart FS9 at selecting of the aircraft.I don't need this really as you said.Sincerely,Kan-ichiro Fushihara
