They never wow you with an upgrade price either especially on 32c. The authorization is simple, you don't have to be online. You can install it on every machine you have. As for me I can't really get into this software.
I think it's in My Documents. They don't even give you the option of where to install. You can move the loops but not the loops and instruments folder if you want their Vita instruments to work. There was a rant about that one their forums.
These are just as responsible for the price reductions on the VST market. There people making great free ones and then people start buying their paid versions.
