Error in opening simulink block in the model through GUI for standalone exe.

I want to load PID block through GUI & convert this to stanalone executable. I tried with below options: 1. Deloytool: PID block is opened through GUI & used deploytool for exe generation. This exe is throwing as error stating undefined function 'uiopen' {which i've used for opening model through GUI} 2. Simulink Coder: I've called GUI through preload function in the model & created exe of model. This exe only creates .mat file of the outputs & doesnt pop out GUI
