I just started getting the fatal error messages with FSX. FSX will then restart but again will fatal error. After two or three of these I get the big red stop sign saying I should reboot. When I clear the message, I have the following dialog box open. "This feature requires that (smartassembly) is available on this computer".Rebooting only starts the error process over again.Checking the event viewer, the error seems to be related to visualfx.dll.I have Win7 64bit, FSX fully upgraded.Was working fine, then last night I added FSUIPC 4.6 and purchased Eaglesoft SR22 for FSX and installed that. I also have UT2, PNW NA, UTX USA,Canada,Alaska, REX and GEX.Any suggestions on how to proceed with the troubleshoot would be apprecated.Thanks,Ken

I have the same problem! :( Eventhough I have nhancer, follow Nick Needham http://www.simforums.com/forums/forum_posts.asp?TID=34141&PID=198187#198187 ://http://www.simforums.com/forums/for...=198187#198187 ://http://www.simforums.com/forums/for...=198187#198187 ://http://www.simforums.com/forums/for...=198187#198187 suggestions. I have good framerates in cruise 15-60 jumping.I do use in tweaks:Bufferpools=200000000[JOBSCHEDULER]AffinityMask=4094But suddently flying over Germany, A fatal error occours. Which brings me to the thing that I seem to CTD most of the time. I did manage to fly in Australia with outh CTD.I flew an Flight1 super-80 Pro, Scenery is Mega Airport Frankfurt, German Airports Bundle 3, UTX Europe, GEX Europe, German landmarks.And for the enjoyment of the community here is the list: My FSX these days: The other day I tried to fly above Dubai With the freeware Dubai X installed. Never succeded because of No more available RAM!! Dubai X is bad; maybe so unstalled again.And the trottle in no arm'ing just travels up and down in all planes, idle is hopeless. Tried some calibration fsuipc but can't get it to work.PMDG 747 goes Waco in V NAV sometime during the flight, CS 757 bad working AP, CS 727 CG in the nose and unflyable, Concorde X INS not initializing and loading ADEC cards. When I do Warp flying with Wilco 777 and move the plane in map function; the plane goes bananas.And Trustmaster refuses to update their software to Hotas Cougar so it "blue select freeze" in W7.A FSX flight simmer - here me - when I crash; I never reach to crash my aircraft because a CTD gets first!
