Yamaha gtr processors (ur44) in Cubase 6.5

When I’m in the “hardware” in the menu Device (Mixer), I can only pick Reverb from ur44 or COMPRESOR from ur44 (chn strip), but offered no Yamaha GTR processors. How do I get them? I use Cubase 6.5. Please help me and thank you.

Its a separate license, that’s one thing, The Yamaha Classics can be used as inserts within the daw, but only for monitoring on the interface, if I am not mistaken.

Also, they have a separate installer, but it should be with the other tools.
