PackagingResults:Error: Error Launch failed! Unknown Error

Hi,
I’m pretty new to Unreal engine and have a problem: I can’t launch my Game via the launch Icon. Hitting play works fine. I first let the build process finish before I tried to launch but I always get the message “PackagingResults:Error: Error Launch failed! Unknown Error”. The error also occurs when I try to launch one of the preset levels so I don’t think it’s related to my project. The attached log is from creating a new project using the third person template, building that and then launching. hope you guys can help me let me know if any additional information is needed.

thanks in advance.

Ok I managed to solve the problem myself by installing the Editor Symbols for Debugging. Just in case someone else runs into the same problem.
