Just curious, how can I determine which version is installed. As soon as I saw the post for the newest version, I downloaded it and all the liveries again. After completely removing the 747 and liveries, I installed the package and all liveries again. When checking the "aircraft.cfg" file I see the heading://///////////////////////////////////////////////////////02NOV07//VERSION 2.00.0031// //PMDG 747-400/400F for FSX///////////////////////////////////////////////////////Is this what it shoud read or how else may I determine?ThanksWilbertAbit AW9D-MaxThermaltake W0106 700W PSUIntel QX6700 QuadcoreVista Ultimate 644x1G Ballistix Tracer (PC2 8500)2x150GB SATA WD Raptor - Non Raid2x320GB SATA WD SE16 - Non Raid2x IDE Light-On DVDRW 165H65BFG 8800GTX OC2 768MB 626MHz Core Clock - nvidia 163.753x SILENX 120X25MM FANS + 2x 10in XCLIO Wind Tunnel Case FansDanger Den Water CoolingEnermax temp/fan controller

You have the most up to date version, their were 29,30 and 31 available.....//VERSION 2.00.0031is the last and correct one.You can doublecheck as follows.....(1) In FSX, PMDG folder, README_PMDG_747400_FSX will show that version number(2) In the PMDG folder, NAVDATA subfolder, the fmc_ident will show[ident]NavData=AIRAC-0710OpProgram=SEP27OCT24/07CoData=EAG-0710The version 30 was sometime in June, Airac-706 I believe...Reider

You can also right-click on PMDGOptions.DLL and it should show 10.0.61355.17If it shows .16, it's older.I'm writing a small utility to help out with these things - it should be ready within the next couple days...
