Thanks for the answer coma, I ended up just d/lin a torrent and installing that, then updating through impulse. To be honest, I'm not sure where to find the preferences window, I have explore, community, my softeare, and my games, and when I right click the system tray icon, the settings option didn't have what I was looking for.

You need that preferences menu placed somewhere else, like in the contextual menu or pop up the first time a user installs impulse. There's no obvious tell that the logo is actually a button.
