Trying HSO SE from iso file (*)

Hi all,
before buying it (only 99$), i would like to test HSO SE…
so as i do not have the dvd trial (i upgrade Cubase 6.5 from Cubase Artist 6.5) i download the iso on that page (*) to test it, i install the iso on my Mac… and i look everywhere but i do not find any way to temporary register HSO SE…

so is it possible to try it?
cause i may be interested to buy this sound bank (even if i own many others), but i think it is normal i wanted to test it before buy it

really need someone help me…

thank you
