Something's wrong with your license, or your MathWorks.com account's linkage to that license. Contact your school's Matlab administrator; your IT department should know who that is.

Please try to run the following in the MATLAB Command Window:

>> opengl software 

And then try opening the Add on explorer again. It worked for me.

If that works, you can save the preference so that MATLAB always opens with Software OpenGL by running:

>> opengl('save','software')
