Set up firecontrol first time

I’m going through the set up and I’m trying to post prosses for the first time. its telling me to down load ‘Langmuir Systems Fusion 360 for Fire Control Post Processor’ file (what is this I thought I’ve downloaded all the necessary programs). and find the file and copy it in fire control. the problem is i cant find this file, when I go on the downloads page I don’t see this exact download and I already downloaded fire control and it installs automatically

if you’re using fusion360, click on this one:

follow the steps to copy and move it/paste it in the the fusion folder.
