Unreal Editor 4.7.2 closes on startup

I just downloaded the Unreal 4 engine and updated to the latest version of 4.7.2. I am using Windows 7 64bit Enterprise edition, so I went ahead and downloaded the required SP1 update before installing Unreal 4. The issue I’m having is that after I click the Launch button it seems like the Unreal Editor is starting, I get the initial loading screen and the percent that it has loaded so far. Once the loading reaches about 70%, the Unreal Editor loading screen disappears and nothing happens. So far I have tried the following based on the solutions proposed to other users:

  • Tried using a different user that has administrator right.
  • Updated video card drivers, I am using ATI Radeon HD 8600.
  • Installed and Reinstalled several times.
  • Checked Task Manager, UnrealEditor.exe never showed up during startup.
  • Checked logs, and was unable to find what was causing the issue.
  • Installed Unreal Tournament Mod editor and was able to use that editor just fine with no issues.

Hi NGol,

Could you post your entire dxdiag (system specs) and Log files? Here is a link that shows where to find the log files.

Also, follow the instructions towards the bottom of that page to generate your Debug logs and post them here as well. They are a bit different from the standard logs.

Thanks,

TJ

Here’s the requested log files for the launcher and DxDiag.

One more thing to try to help us narrow it down. Try bypassing the Launcher altogether and open the UE4Editor.exe directly. Let us know if you can or if it still closes.

Here is the file path you can find the .exe in (yours may vary slightly):

C:\Program Files\Unreal Engine\4.7\Engine\Binaries\Win64

Opening the editor directly results in the same issue. The loading of the editor reaches about 70% and closes. I also checked the crash report and it reports no crashes.

Hi NGol,

Can you try going to this folder: “C:\Program Files\Epic Games\Launcher\PatchStaging” and delete the 4.7 folder there and try and download the engine again? It sounds like something got corrupted during the download process.

I have previously installed and reinstalled the 4.7.2 version of unreal 4 about 3 times and I still have the same issue. However, I went into the PatchStaging folder and it was empty. I’m wondering if there is a possibility that my video card is no longer supported. I checked the drivers for it and it doesn’t seem to have any new updates for 2015. I have also tried downloading Unreal 4.6.1 and the result was the same.

Dear Maximusdb3 and Ballard,

I have resolved my issue by using a solution posted by another user who had simillar problem as I did. In this thread: 4.4.0 Fails to launch - Platform & Builds - Epic Developer Community Forums

I ran cmd.exe as an administrator and wrote the following lines into the prompt:

  1. netsh winsock reset catalog

  2. netsh int ip reset reset.log hit

I then restarted my machine and the editor loaded fine with no issues. I’m not entirely sure how this fixed the issue but it worked. Thank you very much for your support. I hope anyone else having this issue try this solution.

Thank you.
