Issue:

I'm getting a "Cannot start due to license error. Error using save..." window after I enter my license code.

Possible Solutions:

We've seen this error emerge on some older versions of macOS. It's related to the matlabpref.mat file being write locked. Use the following steps to fix the problem:

  • Note the file location in the error message.
  • Open a Terminal window and navigate to that folder. It should be something similar to [but not exactly] this command:

cd "/Users/username/Library/Application Support/MathWorks/MATLAB/mcr_v99/Solo_MIA_95124433-2ac1-4d87-86a5-810b5388a433/"

  • At the terminal type the following command (you will be prompted for your password to run it). This command will give "write" permission to the owner of the matlabprefs.mat file:

sudo chmod u+w matlabprefs.mat

  • Restart Solo (or Solo variant) and enter your license code.
