I have MSP 12 and Audio Studio 10

In addition two add-on packages :

Izotope Audio Enhancer Plug-In and Vocal Eraser plug-in

I have installed both ....   Vocal eraser appears under tools ............ but I cannot find Izotope Audio Enhancer Plug-In  where do I find this .. or is there something other than install required.

I have licenses for both - but had no 'prompt' to input license details.
