Win 7 UE 4.4.3 Closes during launch splash screen

Thanks!
Here it is I hope it helps solve this.

Were you able to find a log in the folder I mentioned?

this is all there was

Okay, see if there’s one here:

C:\Program Files\Unreal Engine\4.4\Engine\Programs\CrashReportClient\Saved\Logs\

There is no crash report folder

All I see are

Okay, one last thing to look for, please. Follow these instructions about getting Verbose Logs from the Launcher:

Just the bottom part for the Verbose Logs.

Alright, there the log. I followed the directions step by step.

Hey Drewseph,

Can you try running UE4Editor.exe from your engine folder? You can find it here:

C:\Program Files\Unreal Engine\4.4\Engine\Binaries\Win64

I ran the exe and it closes before getting past the initial grey splash screen

Okay, one other source of information that might be helpful for us. Shift + Right-Click in the white space in that folder and select “Open command window here”. In the Console window that opens, type “UE4Editor.exe -stdout > outputlog.txt” (without the quotes). That should create a file named outputlog.txt in that folder. Please attach that as well. I apologize it’s taking some time to get to the bottom of this, and appreciate your patience.

Also do a quick check and see if there’s anything here:

C:\Users\<WINDOWS USER>\AppData\Local\UnrealEngine\4.4\Saved\Logs

Okay I checked the logs folder and there was a log in there, I attached along with the output file

Thank you very much for that information. I’ve sent all of this along to our developers to look at and they will get back to you as soon as they can.

In the meantime, if you have another machine to try installing the engine on, please try there as well and let us know what happens. Thanks again for your patience!

my only other machine is not strong enough to run the engine, its a very underpowered system.

Crashes usually are placed in the following location:

C:\Users\[username]\AppData\Local\Microsoft\Windows\WER\ReportQueue

Please check if you have folders named like this AppCrash_UE4-[gamename]-[guid]

That folder is empty

Is there any word on when I should hear back from them?

Jaroslaw is looking into the issue for you now.

Drewseph, thanks for the files. What you’re seeing seems to be a rare problem - possibly related to a particular PC configuration - that I’ve seen posted by someone only once before.

Without further details on what exactly is crashing, it will be impossible to figure out what’s happening. Would you be able to build the Editor from the Github source code in Debug mode and assist me with debugging this problem?

In the meantime, to unblock you, please try disabling the UdpMessaging transport as follows:

  1. Open the file /Engine/Config/BaseEngine.ini in a text editor, i.e. Notepad

  2. Add the following lines at the bottom:

    [/Script/UdpMessaging.UdpMessagingSettings]
    EnableTransport=False

This will also disable some other features in the Editor, particularly UFE related functionality, such as profiling, but you won’t need that in the beginning. Hopefully we can figure out what’s going on.

Another thing you can try is this: if your PC is not connected to a wired network (i.e. only WiFi), please try connecting it by wire to a switch, router or internet gateway. Please let me know if that makes a difference, thanks!

gmpreussner ,

I’ll try to figure out how to get the source code. I’ve never done something like this though, but there’s always a first time. Is there a guide available on how to do this?

I’ll try those changes to the ini as soon as I get back.

I am not able to connect via wire to the internet, wifi is the only option here.
