unable to install the sound packs...

Hello everyone

I am using ableton live 9 and the ableton live 9 beta together with my push on a windows 7 - 64 bit machine.
yesterday i purchased the mad zach soundpacks volume 2.
So what I did was trying to add a few of them (after I unzipped that huge 1,2 gb file) within ableton live.
But the packs don't show up. I have no clue what to do or try now so i can use/find those packs within my ableton live software. It's the suite I am working with, so I did install packs before, which was easy and worked without a problem, but this time I seem to be lost.
Any clues on what I should do to make those yummy packs appear in my packs list or somewhere else...?
