MATLAB: Do I receive Error message while running demos in Aerospace Blockset 3.9 (R2012a)

Aerospace Blockset

I am using some of the block from Aerospace Toolset and the block input and output names are missing. Rather than displaying the block name, it shows "???".
I tried running the aeroblk_hl20_vr demo and it gave me the following error message:
Fail to Initialize.
When I try to locate one of the demo files, I have the following output.
>>which -all aeroicon
C:\MATLAB\R2011a\toolbox\aeroblks\aeroblks\aeroicon.m % Has no license available

Best Answer

A product license is required to run demos and use blocks for Aerospace Blockset.
Please confirm that the following output has Aerospace Blockset
