This error will occur if the path to mlm in your license file is incorrect. To resolve this error, open the license.dat file with a plain text editor and correct the path to mlm.

The DAEMON line specifies the daemon type and the path to the daemon. For MATLAB, this is:
DAEMON MLM <path to vendor daemon>
The location of the daemon depends on your operating system.
Windows
The daemon will normally be located here:
$MATLAB\etc\win64\mlm.exe
Linux
The daemon will normally be located here:
Mac
Prior to R2011a, MLM was named lm_matlab on Linux and Mac.
Once you have made the changes to the license file, you must stop and start the network license manager. (Do not reread the license file: reread is not supported by the MATLAB vendor daemon.) For more information on stopping and starting the license manager, please see How do I start or stop the MathWorks Network License Manager?
