Why do I receive the following error:
MathWorks Licensing Error 13
A licensing error occurred while trying to use <PRODUCTNAME>.
The license file you are using is missing the required SERVER and USE_SERVER lines.
Contact your system administrator to get the correct license file and reactivate your license on this machine.

This error indicates that the SERVER and/or DAEMON lines are missing from the license file.
The SERVER and DAEMON lines are added to the "license.dat" file when the network license manager is installed. These lines should appear just before the INCREMENT lines in your license.dat file.
If you need to add these lines to your license file, please see the following article for instructions:
How do I manually configure my network license file for the Network License Manager?
NOTE: Once you have made changes to your license file, be sure to restart the license manager for these changes to take effect. For more information on how to restart the license manager, see the following Related Articles:
How do I start or stop the Network License Manager?

The links in this answer are all dead. Please format the text properly, such that the < and > characters appear without an interpretation. A link to "Solution 1-18PYZ" would be useful. Thanks.

network.lic files go on the client machine, and do not have INCREMENT lines. The INCREMENT lines go in the network.dat file on the server.
