Hello,I had to re-install the 747-440X for FSX, without FS9.I still have all the initial setups and all the updates.I can not install the ""PMDG747_400_V1R12_FSXFS9_Unifier" update for I get a message that FS9 is not availableI also can not install the ""PMDG747_400_FSX_2.10_Update_Setup" for the same reason, no B747-400x version.It was said in the .txt file of the V1R12 update that we have to completely remove all the B747-400X from the system, that is why I have not installed it in the first place.Must I install the original version first and than the 2.10 version. What about the changes made in the V1R12 version?Are they included in the 2.10 version?????By the way, I am installing now to Win 7. Might that gives ""problems""Hope for an answer.Thanks for listening.Carlos Oosterling
