How To: Install Mad Zach Sound Packs (Ableton)

how do you open a new mad zach .als file without opening a new ableton session?

I just bought the midi fighter 3d and downloaded the mad zach midi fighter 3d pack that came out in 2012... it doesn't seem to be mapped right. Was it not designed for ableton 9? I'm running the trial version too, if that changes anything....

How can I install multiple packs. like assign one to each deck?|
