Crash to desktop without error message

xbox controller seems never ending story ( similar to usb unplug, or bluetooth )… may be the newest topic around is: CTD - Wireless Xbox Controller disconnect

Interessting might be… which messages is logged in event viewer in this case ?

I had this issue with Windows 10 Insider and new OS releases (for many months) didn’t help it work. Sent a Zendesk and after some back and forth, they came back with the below remedy.

This is currently the only way I can run MSFS on Win10 Insider:
(if this works, you can make a shortcut with the “cmd.exe …” action and leave it on the desktop)

Loading issues (stuck on loading screen, long loading times, stuck on black screen, etc…) – Microsoft Flight Simulator Support (

If you are stuck on a black screen after clicking **Play** or **Launch**, skip the intro.
1. Close Microsoft Flight Simulator
2. In the Windows search bar type Powershell
3. Select Run as administrator
4. In the pop-up window that appears, copy-paste the following command:

cmd.exe /C start shell:AppsFolder\Microsoft.FlightSimulator_8wekyb3d8bbwe!App -FastLaunch

5. If prompted, authorize the program to run.

Thanks for this, but unfortunately it has made no difference in my case as still black screen for a few seconds and then disappears with no start up
Thanks for the response in any case.

yeah, so many different “problems” makes it hard to give good advice. My MSFS would just start, a few spins in the bottom right, and just sit in a blank window “forever”. Then the ‘cmd’ helped skip the intro part and it’s worked ever since. Hopefully things can be solved to get it more reliable!

Today i had my first screen freeze during a flight from EGGP to EGLC with TBM930
I did the flight twice and the game freeze always on the same place.
ODVOD intersection during STAR procedure to EGLC.
Then i can’t close the game as it is all freeze.
Is anyone experience this isssue too ?


please check windows event log for a “grammar.pggmod” message. In case you find such a message, please report issue here : 100% reproducible CTD at specific coordinates for months [grammar.pggmod]
( and of course in ZenDesk )

My event log say something about mobex.dll fault.
Do you have any knowledge on this one ?

can you show us the message ?.. quickly I found only somewhat about Samsung application ( have you installed the S…studio , may be also LG ? ) … or do you mean a MoBEX Event ?

mobex event.
I only have ASUS XONAR AE on my ASUS pc.
never instaled other one.
I did a clean with Amswsoft PC Optimizer to clean junk files.
And the windows viewer report were erased too. Sorry not be able to provide the windows event log.
I’m about to start the flight again and see what happen this time.
If i have another CTD i’ll come back and show you the windows event report.

yep… this is only event type , not a dll :slight_smile:

Let us know whether you can re-create the CTD at the same coords.

I won’t be able to reproduce the CTD as i just pass on the coords point and i went trough.
Sort out this one.
Now need to check other coords where i have CTD too.

The CTD i was having is at ODVOD intersection north EGMA airport in England.

The other one i have is at HIJ VOR in Spain when i do the flight LEMD to SAEZ on the B787-10

A lot of the cleaning files done by Amswsoft PC Optimizer where on appdata\Local\Temp folder.

Oh well.

I can’t even start MSFS anymore without getting a CTD just before the main menu. This has happened before (it has started with Sim Update 4), has worsened over time (CTD every 2nd time I open the game), but since a few days it has become impossible to even start the game.

Of course, no error message, no logs, only the cryptic Windows event log because why giving your customers a clue about what’s happening, right?

Needless to say, nothing changed on my PC since these problems started to happen and then worsen, and all other games still run just fine.

I think I’ll give up at this point and hope they fix their product at some point. Just like back in October, when clouds started flickering, and they didn’t fix it until December.

I’m just super glad I didn’t invest any more money into this apart from the initial shelf price. I’ll update my product review accordingly. Good luck to everyone else.


… it would be very unfortunate for you if you continue to use this game against your will …

@Gsx31 I wanted to invest in the CRJ But since having these problems there’s no point in purchasing anything else for MSFS

show us the message :wink:

Are this still your PC specs ?

I would be shocked to see this rig launch MSFS back in August. I had very similar spec on release and couldn’t get it it fire up. I had already ordered new hardware at the time but wanted to see if I could maybe pass the old system to my son so he could run MSFS, even dialed back. NOPE.

That GPU exceeds the minimum but does not quite the recommended. I remember some arguments about how the required spec has shifted upwards during development. I would imagine this will continue as DX12 comes in, and new effects are added by developers.

The GPU is borderline yes, but that 6700 plugs into the 100 series MB. It isn’t always about CPU/GPU. Sometimes its about the pipes in between.
