I'm sorry, I have not had any problem at all with W7 64 and FSX. I do have one aircraft that will crash the simulator when selected, but that's not an issue with the OS.

Alright, I reinstalled FSX and FSX Acc. using the instructions from Nick N. (in the thread above) and the problem still exists.  20 minutes flight time and then FSX calls it quits and freezes.
I don't know what it means to have an "overclock" so I really couldn't even tell you if I have any.  The only over-anything I get is an "overspeed."

I'm out of ideas.  But, just in case it helps anyone my system is running an i7 920 @2.67GHZ, 6GB of RAM, and Windows 7 64-bit as you already know.  Wouldn't think that running FSX would be much of a problem.  Worked great on this same computer when it was running Vista Ult. 64-bit.

Bring on the ideas before I drop the disks out of the real airplane (and yes, I will notify the people below according to part 91.15).

I am not sure but does it happen when you are clicking a menu(right click)? If yes, then it might be a UIANIMATIONCORE.dll problem.

Would u mind posting your Error Log here. You can find your Error log in the event viewer.

Try running FSX as an administrator.  I was having the same problem.  Flew 2 flights online with Squawkbox and lots of traffic with no problems.  FSX Win7 64.

Running in admin mode sped up access to menus and all options.  I am running FSX all sliders to the right.

Well, I haven't run it in XP mode, or installed it in XP mode.  I did try running it on Vista compatibility and I did get one full flight in with 3 instrument approaches.  I was thrilled!  Then I ran it again and, alas, the program froze up, again.  I've tried just about every single combination of normal FSX, with/without SP1&2, with/without Acceleration installed... don't know.
I don't think the problem is machine capability as it is brand new with the i7 920, 6G of RAM (DDR3), 1 tera of harddrive space (one HD, no external HDs).
Is there any sort of patch coming out for FSX to run properly on Windows 7, or has Microsoft taken out the programming team that worked on FS?

Hi, I have a similar problem with FSX and Windows 7 (64-bit), however my problem is that every time I touch ground, FSX freezes/lags the hell out of the computer. As stated above, FSX worked perfectly in Vista 64-bit but now I have this problem.

I was wondering if this file 'UIANIMATIONCORE.dll' or 'UIAUTOMATIONCORE.dll' might have something to do with it?

Anyone else had this problem? Any help is appreciated.

Thanks

I had the same issues where FSX would freeze mid flight in Windows 7 64 Professional. I couldn't figure out what it was doing by trying different combinations of settings and such. I was using the new feature of windows 7 that cycles through several background pictures. I had noticed in other games that my PC would hiccup when the background image changed. So I turned that off and now I have a few flights in with no freezing. I think that it would change the background image in windows, and fsx would freeze.
