Alright Here goes I have windows XP 64BIT I also have Air hauler and and off course FS9, Everything was working beutifully, I have been lots of jobs within Air hauler with no problems whatsoever (By the way i have Flight Simulator 9 installed on an external drive.)
Ok now to get to my problem, well I decided to split my Hardrive into 2 partitions Using Acronis Disk manager, After reducing the Volume and recreating a second Partition i Installed windows 7 64bit (NOTE: The first partion is still in place and has windows XP 64bit with Fs9 still installed i did not touch that partition i only installed Windows 7 on the newly created partition)
Now when i dual boot and boot into my original XP 64bit Partition everything works find but when i launch air hauler i get this error (FSUIPC Is not instaled) Funny thing is i look at the status through FS9 And FSUIPC Is installed and registered with Wide FS. i go into The main FS9 directory and the FSUIPC DLL is there along with the FSUIPC.INI And FSUIPC.KEY
