You might receive this warning when the MATLAB license file on your computer has an expiration date set by your Administrator and needs to be updated. If you are the End User of the license, please try the suggestions below to update your license file.

 

1. Check license expiration date

Check the expiration date of the license you are using on MathWorks.com. You may need to renew your license or your trial license is expiring soon. You can check in the License Center from the link below.

6. Delete/move old license files

  • Proceed with caution. Any and all files you delete or move should be backed up in a safe and reliable place prior to deletion. Deleting or moving files may cause them to be permanently destroyed without any way of getting them back.

There are a few different kinds of licenses that can expire:
  • Trial licenses are typically 30 days -- but trial licenses are never "purchased"
  • MOOC licenses -- these are arranged by the university or professor, and can be set for arbitrary expiration dates. The end user (student) does not "purchase" these licenses.
  • A kind of student license that I have not seen evidence of for at least 5 years, not sure if it still exists. Those licenses had to be purchased on-campus and were valid for 4 months, or 8 months, or 1 year.
  • Academic licenses, by arrangement with Mathworks. These are valid for however long was paid for, typically one year, or however long is required to synchronize up with the institution fiscal year.
  • Standard (commercial) licenses, by arrangement with Mathworks. These are valid for however long was paid for, typically one year, or however long is required to synchronize up with the institution fiscal year
