lol im assuming youve never done this before but dw its super easy:
when you press download there should be a little thing that pops up at the bottom of your chrome tab that says something like stick_with_it.zip
when it is finished downloading (should only take a few secs) click on the little ^ next to the .zip file and press show in folder
it should open a file explorer window that shows all your recent downloads. click once on the .zip file and it should highlight in blue. then go to the top of the window and press compressed folder tools
underneath it there should be a button that says extract all, press it. a smaller window should pop up that says choose a location to extract to or something like that, no need to change the location, just make sure the box that says show extracted files when complete is checked, and then click extract
this should take another few seconds, just wait until its done and a new window should pop up, look for the file that says Stick With It (if you look to the right of it should say application) double click and enjoy!!
