ACTIVATING MATLAB FROM OLD TO NEW TRIAL STUDENT LICENCE

Can i just use the activateMATLAB.exe to activate my old licence to a new one without having to dowmload the installer once again since the products listed are all the same? if yes,

How long does it take untill MATLAB is activated?

[Adam Danz]

Yes. Reactivation is quick if not instant.

[Walter Roberson]

Less than 10 seconds in my experience.
