The third and fifth boxes say "There was an error during installation. Undo (all changes, maybe?)."
The fourth box says "Please insert your game disk."
The second box asks where you want to pick the folder to install it in, which installation type you want (small or full) and if you want to make shortcuts in the desktop and Start menu for the game.
And the first box says "Please quit (lit. stop) any currently running (lit. resident) software when you begin setup."
