All vocaloid vocals come with a "Lite" version of the software. You must buy the full version separately. You only need it bought once though to use any Vocaloid3 vocal.

Thats all you need to know, I'll explain why there is a "lite" version though...

The vocaloid2 vocals had both the vocal and the full engine with every vocal, it made the price high because you were buying the full engine every time... The Lite version makes things cheaper by only including a limited version of the software.

Also, having only a "lite" version removes some of the old compatibility issues vocaloid 2 faced with older and newer vocals... Since the vocaloids always had the latest version of vocaloid2, it meant the older ones would have some conflicts with newer versions.

Prima is the best example of this since she was the first vocal to have a version update, she hated being installed over newer vocaloids and you'd have to re-install the vocal with the latest version of vocaloid to remove it. Incidently, it was a mess for the illegal vocaloid versions too, since that was the most commonest place the issues came out.
