I just installed the Vocalise library (via Heavyocity's installer program) on my dedicated samples HD, but when running Kontakt 5 (standalone), it doesn't see/recognize Vocalise.......I just created a new folder for Vocalise (not within my K5 libraries).  I also ran NI's Service Ctr. to see if I first needed to enter the serial, but no show there either. 
 
Does the library need be where my Kontakt libraries are located (which are on the same HD, but a different folder)?? 
 
 
EDIT: I took Smokeyj's advice and moved the library inside my Kontakt 5 Library.......it's working!! Yaaay!!
Thanks Smokeyj!!

Did you try "add new library" in Kontakt (above all of the libraries in the browser)? It definitely has to be activated via the service center.

I had no issues and I installed it wherever I wanted.

Yeah, that's what I tried "add new library" when it said 'couldn't locate library' (something like that). I must admit though that I only tried it once this AM before rushing out the door to get to work, and didn't get a chance to look deeper.
 
EDIT: the Vocalise library is actually below K5 libraries (it's in alpha order)......possibly this may need to be moved up??
