I get this within about 10 seconds of the editor being open with no other input from myself - may have something to do with its compiling shaders after the move to 4.9.1? I’ve tried the usual fix of deleting my saved and intermediate folders but the problem persists.

I don’t have a solution, but just based off of what I’m seeing in the log files, it looks like the hardware survey is failing and causing a fatal error. It looks like an error on line 506 in “d:\buildfarm\buildmachine_++depot+ue4-releases+4.9\engine\source\runtime\core\private\windows\windowsplatformsurvey.cpp”
COMResult = Assessment->get_Info(&WinSATResults);
My guess would be that the Assessment variable is somehow NULL and that line is trying to dereference the null pointer.
Your callstack is different than BobJoel. Can you post as a seperate report on Answerhub and please include the link above as well as a copy of your DXDIAG?
I ma trying to track down the root cause of this issue for you and since we cannot reproduce this internally I may need you to run some tests for me. First, Can you try to run the Editor as an Administrator on your CPU and see if you crash in the same manner?
I ran Unreal Engine\4.9\Engine\Binaries\Win64\UE4Editor.exe as admin and though it brought up the launcher briefly, the editor never appeared. It crashed with this message:

No minidump found for this crash.
I did check for the dump/log files but there was no folder with today’s date generated.
If there’s more I can do to assist you guys in replicating this I’d be up for it. Curious if I go back to the original 4.9 release now whether that would launch or not (it worked fine for the week before I upgraded).
So it looks like the engine is responding to what it sees as a bad DirectX system file. Can you run a check on your DirectX installation (you can use the following link) and make sure that you have verified your installation then see if the crash still occurs.
I’m current on windows updates and ran the manual installation for DirectX 11.1 - unfortunately there’s no option in the installer to verify / repair. It just gives me a message saying “Update for Windows (KB2670838) is already installed on this computer.”
Perhaps I should do a repair / reinstall of windows 7 as there doesn’t appear to be a clean way to to reinstall DirectX. If nothing else I’ll try rolling back to 4.9 before I attempt it.
You might before a complete OS reinstall look back in your system recovery to see if installing in programs, games anything occurred after you switched to 4.9.1 and try rolling those back to see if the solution presents itself.
I didn’t reinstall win7 or do a restore but somehow my issue is now resolved - starts up without a hitch.
I was starting to download 4.9 and before that I grabbed this week’s nvidia driver when I launched the editor one last time and it worked. Thinking they might have had some directx bug ironed out.
