I was just curious if running fsx under vista service pack 2 improves anything. Earlier my fsx crashes when closing down and so I wasn't sure if changing the compatibility. Also, i looked in my event viewer and this showed up also.Faulting application name: fsx.exe, version: 10.0.61472.0, time stamp: 0x475e17d3Faulting module name: d3d9.dll, version: 1.0.0.1, time stamp: 0x48751493Exception code: 0xc0000005Fault offset: 0x00006d1cFaulting process id: 0x2178Faulting application start time: 0x01cce08d541209d9Faulting application path: C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\fsx.exeFaulting module path: C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\d3d9.dllReport Id: 365e0a79-4c86-11e1-b201-50e54934e836Help please ahah

I run FSX under Vista SP2.In general you should always install the latest SPs for all your software, including DirectX, MSVC and .NET Runtimes and SPS.Go to Windows Update and when you're done (it might take several cycles until you get no more updates), defrag your HDD.Cheers,- jahman.

Thanks Jahman, also, do you recommend turning of firewall and disabling anti virus while flying or not?

Keep the firewall, disable the anti-virus.Cheers,- jahman.
