Editor crashes on launch: Unloaded module

Hello,

I’ve recently bought the U4 licence and did a clean install, just to find out I can’t use any of it because of a weird crash when I try to launch the editor. I can’t select a project, nor create one. The editor crashes after some loading time when I click the “launch” button in the launcher. A crash report is generated with the following callstack:

!Id:c4c49509bad909b33ced82af7e6ffc63

Unknown exception - code 00000001 (first/second  not available)

I’ve seen some people getitng the same error, and the only one who made it work could only do it by switching to a different machine. I wouldn’t like to do that only to make this work, so I’m asking for some help with this issue. I’ve tried to launch with both 4.4.2 and 4.4.1 versions, without success.

I’m also sending my DxDiag report if it is of any help.

Hi Haykath,

Sorry to hear you are having this issue. Hopefully we can help you to figure this one out.

First question, have you tried running the “Verify” option on your installation?

Second, are your video card drivers up-to-date?

Third, where have you installed the Unreal Engine to, and do you have any non-standard characters in the filepath?

Thanks

Thanks for answering :smiley:

I’ve tried verifying two times, didn’t seem to make any difference. Tried reinstalling once also. The GeForce Experience program says my drivers are up to date and it doesn’t seem to have any newer betas. The Editor is installed in the standard program files path, doesn’t seem to have any unusual characters.

Okay. Please navigate to the following location:

C:/Users/UserName/AppData/Local/Microsoft/Windows/WER/ReportQueue

The latest file folder there will contain logs and crash dumps which can be useful for us. Put in in a ZIP file and attach it here.

Thanks

Sorry for the wait, here it is:

Hey Haykath,

Sorry for the delay in response. We’ve looked over what you provided, but something seems to be missing. After you crash, can you check the folder again to see if there is a .log file? It’s not included in the zip you uploaded.

If you simply aren’t having one generated, take a look in Unreal Engine/4.4/Engine/Saved/Logs and check if there is a file there.

Thanks

Sorry for the delay. There is a single file in the “logs” folder, called UE4_Win64_MonolithicHeaders_Success.log. The only thing inside is the message: “Just a record of success.” There are no logs in any of the U4 folders in the WER/ReportQueue folder.

Hi Haykath,

The log file we are looking for would actually be located at:

C:\Users\<your user name>\AppData\Local\UnrealEngine\4.4\Saved\Logs

Sorry for pointing you at the wrong location.

Edit:
Sorry, a few other things that I just thought of. Have you experienced the same issue with 4.4.3? I know you had mentioned that you would prefer not to have to try using a different computer to resolve this issue, but are you able to try on a different computer just to see if it does work there?

It did not work with v4.4.3 and it worked just fine in my laptop. But nevermind, I recently bought an SSD and did a clean windows installation on it. U4 works like a charm now.
