what's the min requirement to mod the ARK

My computer: Core I7-6700HQ 8G RAM ,Windows7 64b,
Can’t open the files in the SDK.

unable to open files sounds like a system problem, not a hardware issue.
Your stats are super low, but, it should open. The first time opening will take a long time as it will need to compile shaders and other things. I am assuming its a laptop, and, as such, a terrible graphics card, so, expect it to be hard to work with.
