Mr Thompson, I find this post a little funny as CNC software has not posted the release of X4 on there site just yet. So I am not sure were you got either a link or a copy given to you.
but at this time X4 is not able to run without a dongle. so you need to go take a class at a collage and ask about a Student version for home.
I will say that CNC software is considering the option you are asking for.
