Flash Player 9 on 10.3

Alright, so it appears that 10.3 isn't supported by Flash 10, no biggie, I found the link for Flash 9. It's a dmg file that has two files in it. Flash Player.plugin and flashplayer.xpt

I have no clue what to do with these files. It's not auto installing like everything else I've done (My lifetime with OSX is about, oh and hour or so). Do I have to throw it in a system folder, get an installer package? I haven't the slightest clue where to start. Any help would be greatly appreciated.
