fbDo you happen to know if FSX was running at the time of the Windows 7 update - even just to the menu screen? Remember if you had been in FSX and closed it just prior to the upgrade on some occasions it doesn't close down totally or correctly and that could cause issues.Speculative answer: From what you describe I would suspect that you something "corrupted" (probably very minor) for whatever reason in thw Winsxs folder which is where the FSX dll's, manifests etc reside. I have never seen anyone 'repair' this folder but I guess that it is possible.In Win 7 there is a reliability monitor that records everything that has happened to your system from the date of installation is there any significant error/entry at the time of the 7 SP1 UG? I guess that you also looked in the event viewer in case something was recorded? When you start FSX, in task manager when you open processes how many versions of fsx.exe are running? If more than one try ending one until only one is running and so on.Looking at what you have tried you may be on the brink of a clean install of Win 7 + SP1 plus a clean install of FSX. Whatever you do from now on will always be running on a "corrupted" install and it may never perform as well again. :( I've had issues with win 7 Home post SP1 (but not Ultimate on another PC, or with FSX)in that every time the PC starts it configures to update windows components for the umpteenth time! I did try the Win 7 Fixit Center and troubleshooter with some success - is that worth a try? http://support.microsoft.com/fixit/BTW I could be wrong but these are some other options to consider.PeterH

Thanks Peter.FSX was not running during the Windows update. I have my system configured to wait on updates until I sanction them. Most of the updates take place as I'm shutting the system down for the night. The update configurations take place in the early morning. So, I don't think there was a conflict there.I don't know about the Winsxs folder or whether you can "repair" it. I'm at a lost there.I tried the Win 7 Fixit Center - I ran a few of the scenarios but nothing came up that I could point to.Regarding a new Win7 and FSX re-install - I just accomplished that earlier in the week. Everything at that point was working well. I installed a few of my "flying" aircraft and restarted FSX - all was well. I started re-installing my scenery packages and FSX was working correctly. I don't remember at which point the FSX application started this non-display of aircraft and scenery textures. I tried going back to a restore point but of course that wouldn't affect FSX - just the OS.So, I guess I'm still lost on this one. Thanks for your assistance - I really appreciate it. I guess I'll wait a few more days and then bit the bullet and re-install FSX to see if that solves the problem.Frank

Well, I bit the bullet. I re-installed, re-installed FSX last night. Right now it's working - but for how long?????? Thanks to everyone who provided input to resolving this issue. I really appreciate it.fb

Hi FrankHope you have solved it for good.PeterH

Hi FrankHope you have solved it for good.PeterH

Unfortunately no. Yes, I re-installed FSX. Yes, it started working. I tried to input one scenery package and it stopped working again. I give up. It's not worth the frustration. I don't think one can protect the software from outside changes and problems with the OS. FSX was not designed to be robust.Anyway, I'm done. Good talking to you and thanks for your interest.Frank
