Did it work before? Are you trying to run it on capable enough machine? This kind of error is not really _directly_ UE4 related.

Error code 0xc000007b means invalid image format. Usually happens because of corrupt application files or issues with GPU drivers. Since, you already tried reinstalling UE4 it’s probably your graphics card drivers. If you’re using an NVIDIA graphics card I would recommend you update the drivers. If that doesn’t work try reinstalling your prerequisites: DirectX and .NET Framework. Hope that helps!
