Can't launch my project, UE4Game.pdb not found

Hey there,

I’m currently working on my project “BASimulation”, everything went fine untill today. I continued working on the university computer and overwrode my project with the newer version of it.

The UE4 is installed on E: and my project is on C:.

But now I can’t launch the project (I only can use “play”).


LogPlayLevel: InternalUtils.SafeCopyFile: WARNING: SafeCopyFile Exception was Exception in mscorlib: Die Datei “E:\EpicGames\EpicGames\4.10\Engine\Binaries\Win64\UE4Game.pdb” konnte nicht gefunden werden.

LogPlayLevel: Stacktrace: bei System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

I even tried to reinstall the engine.

I’ll be really thankful for a working solution.

Having same issue. To upgrade to 4.10.3 I had to uninstalled 4.10.2 due to a lack of space on a disk volume. After reinstalling I cannot launch my projects. I get the warning messages like “Epic Games\4.10\Engine\Binaries\Win64\UE4Game.pdb”.

I too have reinstalled twice to no avail.

I resolved this by downloading the Editor Symbols for Debugging. After that the launch worked.

Thank you so much!

I’m having the exact same problem. I’ll try and download the Symbols for Debugging, but it’s a freaking 8GB download that shouldn’t be necessary!
Thanks, anyway.

This fixed not all !

after i create a “empty” Selection_16x.png , and the other mistake gone away.

If you’re still experiencing complications after downloading the Editor Symbols for Debugging, please submit a new thread to AnswerHub because that means your troubles with the engine aren’t the same as Anuki’s.

Hi, where can I download editor sumbols?

In the launcher, right click on the engine and select “options”. It’ll show you some selection boxes, among which you’ll find the Editor Symbols for Debugging.
Good luck!
