Answer 1

Go to /Applications/ right click on your MATLAB app select Show Package Contents look in the bin folder. Its the first item in the bin folder: activate_matlab.sh

[Jinan Al-Asadi]

thank you so much ! however i didn't look in the bin folder after i pressed select package contents, i pressed on activate and then made sure i put in the correct username this time.

thanks, it worked

Is it reasonable to put root as the Licensed End Use?

[Walter Roberson]

@Pol Adillon

Using root as the licensed end user is not usually a good idea. That would force people to sudo in order to run MATLAB, and the resulting session would have write access to nearly everything on the system

The message sounds like you have to run the Activation client to reactivate your license. Did you try this already? If you have no success, the Mathworks support team can and will help you, while the power of the forum ist limited for such questions.

[Manuel Alberto Gámez Rosas]

Hello, one question, where I can find the activation client?

[Image Analyst]

If you have Windows, look under

Start=>AllPrograms=>MATLAB=>R2015a=>Activate MATLAB R2015a

[Manuel Alberto Gámez Rosas]

Sorry, I have mac. Could you help me please? Tks in advance

[Sayak Roy]
