Does anybody know where I can get a copy or license for proworx?

I just grabbed like 10 full plane Koyo 405s from an upgrade project and DirectSoft is easy to get, but the technologist says Koyo is garbage, doesn't follow IEC standards.

I want to learn to program more mainstream PLCs, does anybody know where to get the software?

I'm looking for both below and above board solutions if anybody knows.
