It's version 4.20 of FSUIPC4.dll, i'm playing FSX and it's for Boeing 737 -300,-400,-500 .. OK, i didin't know that it's not for this thread but earlier when i played FS2004 and installed it it worked with no problem, so I asumed it's something about that .. thx

I installed 737 PIC and successfully installed fsuipc but when i want to start with any of boeing 737 aircrafts, it pops that message b733main.GAU problem with other .GAU files too and if I click Run for all of them, it starts flight but i can't use controls in cockpit and if i click Don't Run, when it starts i don't see it at all (cockpit instruments). Does anyone know what to do ? Thanks
