Creating a protected model requires a Simulink Coder license. You as a third party that receives a protected model must match the platform and the version of Simulink for which the protected model was generated.
If you purchased your own Student Version, then you do not have the ability to purchase Simulink Coder. But maybe you are using a university license and the Simulink Coder product would be available for you if you ask.
In order to help you fully, I am interested to learn about the context. Is the professor sharing a protected model? Then I could suggest alteratives. Are you working on an industry model as part of your thesis? Also here I can make - different - suggestions.
