Error installing 400F on FS9

Featured Replies

Hi. I've tried FSX for a while, but I decided to return to FS9. Now I'm reinstalling everything and installed the Queen, the upgrade 1.2 and when I try to install the 400F it says I must have installed the PMDG 747-400 v1.0 or newer ?????????I searched the forum but I have not found an answer. I used the FS_Registry_Repair.exe but I still have the problem.What can I do?ThanksGerry Renve
