Vocaloid3 is confirmed to work on Windows 8 and 64-bit systems.

If you want, why not contact Vocaloid studios Zero-G or PowerFX since they answer in english and aksk directly. Failing that... Try Vocaloid Otaku forums as their usually pretty good at this too.

In general, if the software is not coming from a legal source (ask at VO forums again for help determining this), then don't trust it at all, least if it turns out to be the full version is coming out of the link. :-/
