I'm getting alot of CDT's when I start FSX an load an ACFT. I've noticed it when I tried to load the PMDG 737NGX and ES CitationX. I haven't really isolated down to a conclusive cause yet but over the last week I've gotten a CTD when loading either the PMDG 737 or ES CitationX. Now it's not every single time but enought to be annoying. I've tried just loading FSX by it's self because normally for me I load AS2012 first then load FSX. It did not matter I still got the CDT, either 737ngx.dll or ntdll?.This is a fairly resent install of both my OS (WIN7 64BIT) & FSX(seperate SSD) I've applied NickN tweaks. Don

Don,What flavor of FSX do you have (SP's installed)?Did you do this (replace the W7 uiautomationcore.dll stored under sytem32 with the Vista uiautomationcore.dll) also?Lets see you DLL.xml file.Are you using FSUIPC?do MSFSX default aircraft load ok .. and then does FSX shut down normally also?

Vaughan1. FSX= MS FSX Gold Edition2. I don't know what this is?

FSUIPC 4.758I get radom CTD, like this morning I booted up the computer and started AS2012 then FSX, I got the following CDT's see pic's. The default acft when I loaded one up a couple of times had no issues and would shut down normally. This morning after the rash of CDT's I was able to start a flt using the ES CitationX but once I started taxing to the rwy FSX LOCKED UP? I had to use Ctrl-Alt-Del.Don

Don,What is the folder path to FSX on your pc?I will go look at your dll.xml file now.Ok,Your dll.xml is incorrect (IMO) as far as the loading order ... but others here know much more about it than I do.. so I could be wrong here.You are also using some software that I do not know about.Do you have a copy of your original dll.xml or one that was backed up by another of your applications?I think there is a tool to check it and make corrections.

ntdll.dll crashes are almost always system problems - instability from overclocking, RAM going bad etc, stuff like that.

So what about the other CDT's I posted pic's of? I'll run OCCT again and verify my system stability.Don

Just completed 2hrs 8mins of OCCT with no errors and my highest temp was 70c.Don

Don,What flavor of FSX do you have (SP's installed)?Did you do this (replace the W7 uiautomationcore.dll stored under sytem32 with the Vista uiautomationcore.dll) also?Lets see you DLL.xml file.Are you using FSUIPC?do MSFSX default aircraft load ok .. and then does FSX shut down normally also?

What is this W7 uiautomationcore.dll and how do I aquire the Vista uiautomationcore.dll, can you elaberate more please.Don
