This error may occur if there is...
- An expired Designated Computer trial license and an active Designated Computer trial license for a toolbox
- An instance of MATLAB trying to use a license file from a stored license
- No license information is present on macOS or Linux
- MATLAB is attempting to borrow or use a borrowed product from a network license, but is unable to do so.
On Linux, the borrow key lives in the user's home director with the file name ".flexlmborrow". Please rename this file to something else so that MATLAB does not attempt to use it on launch.
