I can't seem to figure out what software to download
there are many options yet none clearly say "circuit simulator".

You're looking for a SPICE package:
Linear Technology's Simulation Program with Integrated Circuit Emphasis
(LTspice) aka "SwitcherCAD III".

Your posting style:
The gold standard is
to leave the name of the person to whom you are responding
and just enough of the previous post to give "context"
which reminds the next reader/responder
what the last part of the thread mentioned.

Your new text goes BELOW that.
(Note how I did it.)
