UE4 Crashing on start up ( error message)

Hey Everyone,

I have had Unreal for a couple weeks now and it just started crashing on the start up. Does anyone know how to fix this? I’m not sure where to locate my Logs and such. Any help would be appreciated!

My Computer- GPU: GeForce GTX 760, CPU: Intel Core i7-4770k 3.5GHz, RAM: 16GB, OP: Windows 7 64-bit


Hey unreal_artanddesign -

The .LOG and .DMP files are from your [project]\Saved\Logs folder. Additionally, you can please send us the CrashReportClient.log file located in C:\Program Files\Unreal Engine\4.0\Engine\Programs\CrashReportClient\Saved\Logs.

There should also be a long string of characters which pop up when the engine crashes if you could submit your crash and then send those characters as well.

Also, Can you be more detailed about what was happening when the crashes started? Were you working on a specific level or project? Is it crashing before you even get to the project or after you select the project to open?

Let us know and we will begin to track this problem down for you -

The same thing is happening to me. I just got the engine today but I can’t even open up my first project. when I press the launch button I see engine editor icon pop up but shortly after the crash report client opens and it says SIGSEGV: invalid attempt to access memory at address 0x3. Please help me


We’ll be glad to help you on your post here:
