Cubase 10 and Waves Z-Noise plugin: problems?

Hi. I am working with Cubase Pro 10 (@ 24bit/44,1 khz) under W7 64 bit.
I have bought Waves’ Z-Noise plugin, installed and activated, just like I did with all others Waves’ plugins I bought in the past.
But this plugin does not appear within the available plugins; I’ve tried many times but no way, it’s not there.
Did anybody experience the same problem? any solution?

Be sure to check Plugin Manager. If you’re using a non-default plugin list, new plugins aren’t automatically added to your custom list.
