OK I bought the upgrade to MP2 at 2:30PM, it's 5:30PM and I'm just about halfway through installing it... On OSX anyway, you have to manually open and go through the dialogue to instal all 17 .dmg files. The initial installer is not a trusted developer on OSX, right click to install etc. It also OSX has to verify every single dmg file, this takes minutes for each one on top of the whole process. It's looking like 5 hours to install a sample library. NI Komplete Ultimate at ten times the content doesn't take as long.
Please, for the sake of your customers, fix your installer on OSX.
