PKG files can't install (fatal error)

I checked out your graphics card and processor's features.
The processor is fine I guess because it has SSE, SSE2, SSE3 and SSE4a (It's a weak CPU though, you'll probably struggle using RPCS3 with it).
However, your graphics card reportedly only supports up to DirectX 11.2 (Source: http://www.amd.com/en-us/products/graphi.../7000/7700 ). You won't be able to run the emulator with DirectX then, because it only runs with DirectX 12. OpenGL is much slower than DirectX and I heard stuff about it being removed in the future.
I don't know why any of this would be related with .pkg installing annieways. Do you have the .rap file associated to the game in place?

rpcs3 needs SSE 4.1 for some thing that this Phenom CPU doesn't support.
