Packaged game crashes on startup

Does anyone know how to debug a mini dump file? Every time I try and debug it the source says it cannot be found. I have UE4 engine symbols downloaded via the engine library. I have all my symbols set pointing at the packaged game exe & pdb files in the binaries folder. I have ensured I have debug files enabled in my UE4 project options. Is there anything else I may be missing? I am doing this all on the same machine as well.
