Mandrill version 0.3

I have just installed the latest version of Mandrill 0.3.
I ran the standalone Mandrill exe file then
loaded rhino+grasshopper.
I then loaded the example but I do not appear to be able to
get the gh component to recognise the Akai APC MINI midi controller
as shown in the uploaded image.

What am I doing wrong?

Many thanks

I forget the specifics, but did you create the required environmental variable? I only used mandrill once or twice. I think the documentation describes the instructions for creating the variable.
