What do you see when you run the following command? [status,errmsg] = license('checkout','Identification_Toolbox')
Also the system requirements for System Identification Toolbox are:
  • Requires MATLAB
  • Requires Simulink for using toolbox blocks
  • Signal Processing Toolbox recommended
  • Control System Toolbox recommended

I have the same problem. As a result I cannot run idnlgreydemo11. When I run the suggested command I get... status =
errmsg =
'License checkout failed.
License Manager Error -5
Cannot find a license for Identification_Toolbox.
Troubleshoot this issue by visiting:
Diagnostic Information:
Feature: Identification_Toolbox
License path: C:\Users\hannajo\AppData\Roaming\MathWorks\MATLAB\R2017b_licenses;C:\Program Files\MATLAB\R2017b\licenses\license.dat;C:\Program Files\MATLAB\R2017b\licenses\network.lic
Licensing error: -5,147.'

john hanna: That license path hints that you are normally getting your license for System Identification by way of a network license, and that at the moment your network license server is telling MATLAB that it has no entries for that toolbox. The error message would have been different if it knew about the toolbox but had run out of available licenses.
