Every time I run FSX it gives me a fatalerror after period of time >> usuallybetween 15 to 30 minutes after start.Does not matter where the aircraft is or what it is doing. There is nothingobvious / specific that prompts the error.Hardware > i7 930, EVGA GTX480, 6GB gSkilland core temp is ~52 deg max (FSX running),Enermax Galaxy 1250 PSUOS is Win 7, 64.FSX > MS Flight Simulator X, Gold Edition AccelerationI have FSX and add-ons set for Win XP SP3compatibility and "Run as Administrator"enabled. No unnecessary programs or services arerunning in background.EVENT VIEWER gives similar results followingeach fatal error occurance (EV Log below)Suggestions for a fix are welcome?Thanks,Ken Boardman Related events from "EVENT VIEWER" Log Name: ApplicationSource: Application ErrorDate: 8/6/2010 9:42:28 PMEvent ID: 1000Task Category: (100)Level: ErrorKeywords: ClassicUser: N/AComputer: Kens-PCDescription:Faulting application name: fsx.exe, version: 10.0.61637.0, time stamp: 0x46fadb14Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000Exception code: 0xc000001dFault offset: 0x02fa2c58Faulting process id: 0x628Faulting application start time: 0x01cb35e8b5f9992bFaulting application path: D:\Flight Simulator X\fsx.exeFaulting module path: unknownReport Id: 2e46ae1c-a1de-11df-995a-001fbc026903Event Xml:<Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Application Error" /> <EventID Qualifiers="0">1000</EventID> <Level>2</Level> <Task>100</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2010-08-07T04:42:28.000000000Z" /> <EventRecordID>6165</EventRecordID> <Channel>Application</Channel> <Computer>Kens-PC</Computer> <Security /> </System> <EventData> <Data>fsx.exe</Data> <Data>10.0.61637.0</Data> <Data>46fadb14</Data> <Data>unknown</Data> <Data>0.0.0.0</Data> <Data>00000000</Data> <Data>c000001d</Data> <Data>02fa2c58</Data> <Data>628</Data> <Data>01cb35e8b5f9992b</Data> <Data>D:\Flight Simulator X\fsx.exe</Data> <Data>unknown</Data> <Data>2e46ae1c-a1de-11df-995a-001fbc026903</Data> </EventData></Event>----------------------------------------------------------------------Log Name: ApplicationSource: Application ErrorDate: 8/6/2010 9:42:28 PMEvent ID: 1005Task Category: (100)Level: ErrorKeywords: ClassicUser: N/AComputer: Kens-PCDescription:Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing.

Exception code 0xc000001d is STATUS_ILLEGAL_INSTRUCTION (i.e., the code tried to run an instruction which doesn't belong to the processors instruction set). This combined with the fact that your event viewer is showing the reason as "Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing." Your post indicates you installed FSX on Drive D which I assume is NOT the default location for FSX installations and maybe simconnect was not properly installed causing a network connection issue. It could also be an issue with your CPU being overclocked too much and not being able to read the instructions. Do you have all the Microsoft Visual C++ Redistributables Libraries installed (as suggested by NickN in his excellent article on setting up FSX (http://www.simforums.com/forums/forum_posts.asp?TID=29041)? I would also make sure the latest dotnet software (Google DOTNET) is installed as developers use these programs to program addons and installation of the software (including FSX). Hope this helps.Best regards,Jim

Thanks for the Tips Jim.What is simconnect, when does it install (when FSX installs?) and is therea practical way to confirm whether (or not) it was installed correctly?I will examine NickN's article >> thank you for the link.Best regards,Ken

According to the Simconnect SDK: The SimConnect SDK can be used by programmers to write add-on components for Microsoft ® Flight Simulator X. Add-on components for Flight Simulator X can be written in C, C++, or, if the managed API calls are being used, any Microsoft .NET language such as C#.net or VB.net. Typically the components will perform one or more of the following:Add the processing for a new complex gauge, or other instrument, to Flight Simulator. Replace Flight Simulator processing of one or more events with new logic. Record or monitor a flight. Extend the mission system of Flight Simulator. Create and set the flight plans for AI (non-user) aircraft. Set different weather systems. Enable new hardware to work with Flight Simulator. Control an additional camera that the user can optionally select to view. You can get more information about it, to include proper installation by checking out the Simconnect Forum here on AVSIM...Best regards,Jim

Hi Jim, Thank you for the Simconnect info. I finally successfully completed a 2+ hour FSX flight in Wilco A318 (DEN to SNA). Had only FS Flightkeeperrunning in background. I'd noticed that Wide FS Server had been enabled in FSUIPC. Since I'm not presentlyusing Wide FS, I decided to try disabling it. Also changed graphics filtering from Bi-Linear to Anisthropic.Can't say which one (if either) made a difference; but I'll be trying another flight very soon. BTW, I see a lot of "heartburn" regarding Simconnect reinstallation issues. Most reports indicate thatit's nearly impossible to successfully reinstall it without reinstalling Win 7 first ~:\ I tried deletingone of the (three) Simconnect.dll files from it's folder and not only could I not delete it, but I wasnot allowed to change permissions for it's folder to enable deletion. Those who have successfully deletedit have discovered that they are then not able to correctly reinstall it so that it works properly. Veryugly situation and someone needs to be spanked ~;)Best regards,Ken Best regards,Ken Boardman

Yes, I agree. Here's a good link to the proper method for reinstalling simconnect issued by the guy who is the developer of FSUIPC: http://forum.ivao.aero/index.php?topic=95115.0. And here's more info from Microsoft regarding Simconnect and the importance of install the Visual C++ and DOTNET software. I can see why it would be difficult to uninstall it as it is the communications device for FSX with other programs and hardware. As I understand it, it is the replacement for FSUIPC.dll but don't get rid of FSUIPC as a lot of addon developers still use the freeware version for their products.Let's cross our fingers your issue has been resolved!Best regards,Jim
