Wrong forum though. Eventually you'll be moved over to the CTD forum by the forum administrator. You can start by trying this fix - http://forum.avsim.net/topic/273341-heres-the-apparent-fix-to-fsx-crashing-win-7-x64/. It worked for a couple of people who had a similar problem with the menu crashing. As you will see in the link, I don't agree with the concept at all but it's worth a try. The uiautomationcore.dll comes with Microsoft.net and, for fsx (it being an old program), you need versions 1 thru 4 of Microsoft.net installed as Version 1 was the one used by programmers for FSX/Acceleration. Later addons require later versions. They are not backward compatible so the version that came with Windows 7 (Version 4) is not backward compatible to FSX. When you install FSX/Acceleration, the appropriate version will be installed as it manages fsx, including memory management. You can check to see what versions you have installed by looking in C:\Windows\Microsoft.net\Framework. You want the 32 bit versions installed. If a 64 bit version is installed that's okay as it was probably installed by another piece of software.

 

Best regards,

Jim

Hi Jim

Sorry for putting this in wrong place, new to all this!

I tried the the uiautomationcore.dll into the FSX folder but no joy.

I've checked my Microsoft.net framework and have

V1.0.3705

V1.1.4322

V2.0.50727

V3.0

V3.5

V4.0,30319

I also have the file in the System32 folder

V7.0.0.0

There is also a 64 bit version

Where to from here?

regards

Andy

Have you got the Aerosoft AirbusX?

Andy - just for reference, PaulJ here on AVSIM posted some excellent tools regarding Microsoft.net on the CTD forum - http://forum.avsim.n...ferent-crashes/. You have all the latest versions of dotnet installed. As I stated, you most likely will have all these versions as they are installed with FSX and FSX addons if they are not found during the installation. Just wanted to make sure you had them all. Menu crashes have also been caused by video drivers. If you recently installed a video driver and the crashes began to occur, this could be the problem. Sometimes a driver will not work well with FSX and individuals go back to the previous driver. You can try that too.

 

I was not surprised the uiautomationcore.dll "fix" did not work. It's truly strange how that "fix" works for some and not for others having the exact same issue. Everyone likes a magic bullet though.

 

Since it's the NTDL.dll my theory is that your system is taking up too many resources and, when you click on the Menu, it takes additional resources. If your system is not tuned/tweaked properly, this additional action could be causing the crash. Nick (NZ255) may have a great suggestion too as any payware aircraft usually takes up more resources than the default.

 

Since you got the infamous Exception Code 0xc0000005, Memory_Access_Violation, you should be looking at your memory configuration too. Make sure the frequency, timing, and voltages are all proper in the system BIOS. The freeware CPU-Z provides the correct data under the SPD tab. You should also check your virtual memory (page file) and make sure it is set to 'system managed size'. This seems to work best for FSX. Changing virtual memory can be found by clicking on the Start button, typing Virtual Memory in the search bar, then looking up and clicking on How to Change Virtual Memory Settings (or something like that). The default setting for Windows 7 is 'Automatically manage paging file size for all drives' and I was seeing some unexplained crashes (not with FSX) until I changed that to 'System Managed Size'. They look like the same setting but evidently they are not. This recommendation has fixed memory crashes in FSX for many. FSX is an old program and I suspect it's still using old memory technology.

 

Another possible solution would be to rename your FSX.cfg to FSX.orig then restart FSX and let the config rebuild. If the crashes stop, then we know the culprit and you can slowly begin tweaking the FSX settings by moving the sliders up slowly. If it did not fix the problem, then delete your FSX.cfg and rename your FSX.orig back to FSX.cfg.

 

Scenery addons could be causing the crash too. You can disable all your scenery in the Scenery Library down to Propeller Objects by unchecking each scenery, click okay, then go fly. If the problem goes away, it could be one of those addon sceneries. Just enable one, run FSX, then enable another, run FSX until the problem reappears.

 

Hope this helps.

 

Best regards,

Jim

Hi Nick

I don't have Aerosoft Airbus X. It's one of the few I don't have.

Andy

Exception Code: c0000005

 

Google the above! This is a common error in apps, not just FSX. It indicates an error from the CPU not the application. The app is just tripping on it. It could be caused by an over aggressive Overclock or a HW problem. This error can occur at any point in the program, so the module it was in is not necessarily significant. It's just what FSX was doing at the time. I see people reporting this a lot in the sound.dll module. (Which is probably one of the most accessed modules in FSX)

Thanks

Hi Jim

This is very interesting and most helpful.

I have heard about video driver problems and will check it out.

Memory, this is vey interesting as I do have a lot of additional scenery(Horizon generation X) and aircraft too many to mention.

I have had a couple of waring windows telling me that FSX is using a great deal of memory so I am inclined to go down this route.

Failing this I will try the FSX.cfg change.

We will get there!

Thanks again

Hi Jim

I have spent the afternoon going through your list.

I stripped out scenery, No joy.

Tried system managed size for Virtual Memory, No Joy.

I eventually downloaded Reg Clean Pro and System Opimizer 3.

My system is not crashing when I use the esc key or exit fight in the menu. BUT!

My add on aircraft are now skeletons!!!! I'm flying bits of aircraft around the sky?

Default aircraft seem to be OK.

Any suggestions?

Andy

Oh dear!...Andy - are you using the Shaders3.0 mod from Bojote by any chance?

Are you Overclocking? If so try bringing it down a bit.

Make sure the following line is in the Graphics section of your FSX.cfg: highmemfix=1.

Not to my knowledge.

Don't think so!

Hi Jim

I'm back in now and had a few flights with various aircraft, default and add-ons. Had a couple of strange things but just exited and restarted.

Norton 360 tells me that FSX is using 100% of CPU every now and then.

How do I access the FSX.cfg file?

Oh while your there how do I set my default location to where I want not Friday Harbour?

That's normal, FSX is very much CPU dependent!

 

How do I access the FSX.cfg file?

 

For Vista/Win7 it's in "users\xxxx\appdata\roaming\microsoft\fsx" folder

 

Oh while your there how do I set my default location to where I want not Friday Harbour?

 

Just setup a flight to the airport you want. then save the flight. Then load it making sure you click the "Make this flight the default" optIon.

Andy
