Fatal Error message in flight

Recommended Posts

Hi guys, I'm a new guy,Signed up here to help and get help, like I need now. Got this problem with the NGX,After flying a while (30 mins +) I always get the Fatal Error message when pressing a button in de FMS or selecting a view by clicking right mouse button etc. (Might also be with other buttons etc.)I had this problem before a while ago and managed to fix it, but that was before I bought the PMDG 737NGX.So since I got this beautiful bird the problem occurs again, so I'm pretty sure this bird causes this problem since it worked fine before. It's pretty frustrating. I already tried to fix it again but without succes. The fix I used was replacing the UIautomationcore.dll Now if anybody can help me with this, i would really appreciate it! Thank you in advance, Mo-Airlines

It's well known that the NGX pushes computers harder than ever before. That's why people are getting crashes now when they maybe never did previously.So what is your system? Maybe you need to add more RAM and speed. I don't think the problem is necessarily always the NGX.

Yeah it certainly does push the computer hard but my computer is good enough for the NGX I am sure, the frame rates are high enough when flying the NGX. And I also know for sure the NGX causes this problem, putting any other aircraft through some tests it won't crash but the NGX does.

Sounds like it might be the ui automation.dll error. If you're running Windows 7 x64, I'd look into that a bit more.

I get something similar... not a crash so much as a freeze. After flying for about 3 hours + the whole game just freezes!! I don't see how and why because my system is a high end gaming system and the NGX runs smooth enough!!

Same here. I didn't even manage to finish the tutorial once. Always freezing when the aircraft gets closer to the ground. Tried lowering some settings but so far without luck. Martin

Yeah got that too @Thruster57,Find out some other actions in flight causes the crash too, but mostly the view selection. Uiautomationcore.dll allready fixen once, then fsx worked great, untill the install of the NGX, must be the problem somewhere in in!

It's the problem causing problems as is the Fatal Error message, but after installing the NGX the fix will not work and FSX will still crash.Fixing without installing the NGX;Download another UIautomationcore.dll here: http://www.mediafire.com/?mik2mlqdz1w (or anywhere else) And replace it with the original in your FSX directory. If that doesn't work I got another fix which I will explain when needed, just let me know. wink.png

Since I put that "dll" fix into fsx a few months ago along with the Highmem fix I have had no problems with fsx!!

how do you fix the Uiautomationcore.dll what ever that is.thanksjames
You have to insert it into your FSX cfg file which can be found in hidden files, but look at a tutorial before doing so.

Be aware that fixing the UIautomationcore.dll is NOT the fix for the Fatal Error message in FSX when you have the NGX installed! @Shamrock727: That fix was before you installed the NGX right?

The filosofy behind the uiautomationcore.dll fix is this: When you are running on a win7 64 bits system, then replace that dll with the 32-bits version of that dll. This fix is to overcome a crash of FSX when using the right-click contect menu or the drop down menu's from the menu bar. You can verify if you can reproduce that issue by simply right-clicking 20-30 times. without the 32-bits version of that dll FSX will crash. Whether this fix is related to your issue remains to be seen however, but it's worth a try i think. Succes ermee!

I think I got it!! I spend all day reïnstalling FSX and all my add-ons, also the NGX.This time I installed the NGX before fixing the UIautomationcore.dll.(Fixed the UIautomationcore.dll by downloading a new one from http://www.mediafire.com/?mik2mlqdz1w and placed it in the Windows / System32 map and replaced the original one. (Make back-up!)) I have flown 2 medium-hual flights today to test it: EHAM->LGHI and back to EHAM via LGKO to refuel and haven't had any Fatal Error on the flights while I excessively used the right mouse button and the view selection via the menu bar. I will make some other flights tomorrow night to test it some more, meanwhile, you might try this too! MO-Airlines wink.png

Do you replace the downloaded UIautomationcore.dll file with the one in the windows/system32 folder or you put the downloaded file into the main FSX folder? I guess it is not the same thing. It does not allow me to replace the system32 folder's file.

@Shamrock727: Lucky you! I still haven't had any Fatal Errors now so I think it worked! @Onody123: Yes you have to replace it with the one in your System32 folder or else it won't work!You need to have permission to change anything in that folder, I don't know exactly how I did that but I think I just clicked right mouse button on the System32 folder and changed something under some kind of security tab or something. Sorry I can't really recall how I did that.You'll easily find that on google I'm sure. MO-Airlines ;)
