Couldn't launch ..\Win32\UE3ShaderCompileWorker.exe!

[stefanvott]

Hey all,
I've been trying to generate a proper executable installer, which seems to work up until trying to install it. The splash screen does it's thing, the game window opens, then crashes, sometimes with a memory error. When I check the log, it always ends with the following (everything else in the log looks fine):


[0022.51] Critical: appError called: Couldn't launch ..\Win32\UE3ShaderCompileWorker.exe! Make sure the exe is in your binaries folder.
[0022.51] Critical: Windows GetLastError: The system cannot find the file specified. (2)
[0023.05] Critical: Error reentered: Couldn't launch ..\Win32\UE3ShaderCompileWorker.exe! Make sure the exe is in your binaries folder.
[0023.05] Critical: Error reentered: Couldn't launch ..\Win32\UE3ShaderCompileWorker.exe! Make sure the exe is in your binaries folder.
[0023.05] Log: === Critical error: ===
Couldn't launch ..\Win32\UE3ShaderCompileWorker.exe! Make sure the exe is in your binaries folder.

I made a copy of UE3ShaderCompileWorker.exe from my UDK build and copy into the correct folder of the installed game, and it runs just fine. I'm wondering if there is a bug in the cooker or if I'm somehow causing it to leave this file out of the installer.

I'm running the October 2010 build: 9029.

Thanks in advance for your help!

Anyone have any ideas on this one?

sorry to bring back a (not so) old thread
I'm having the same issue. as soon as I put the exe in the folder the game works. however this isn't optimal for a game distribution

Same here.

Are we all using the October 2011 build?


/Ok I got it working.


I had two warnings in Frontend about some MaterialInstanceConstant for the Terrain (no ****ing idea where they came from, have had those warning several times) which couldnt be compiled for D3D/OpenGL. I got into the map package and deleted both files (doesn't affect the terrain or its materials in any way, doesnt need lighting rebuild either) and voila, it works now for me.

So if you have similar warnings, try that.

Oh sweet. Thanks! I'll check that out when I get a chance.
