MATLAB - Can't see methods or properties of a COM object

Question

I am trying to use MATLAB R2016a to access Amibroker via Amibrokers COM interface. I used the following code to create a COM server in MATLAB: AB = actxserver('Broker.Application')

When I use get(AB), Matlab returns 'struct with empty field'. There is nothing in the Inspector when I double click on the AB object.

Any idea what the problem is?
