Why any of the Xilinx products appear in the Hardware Implementation -> Hardware board?

Hello,

I am trying to work with the Zedboard and Simulink but there is no way of getting this working. I am using Matlab 2013b and Xilinx ISE 14.7.

I installed the hardware support pakages, tested the connection and everything is fine (apparently), but when following the zynq_gettingstarted tutorial, in Task 1 I cannot find any of the Xilinx products.

Why is that?

Thanks for your help!
