Why do I receive License Manager Error -140 when trying to start MATLAB?

I have updated MATLAB to R2017a, and have applied the new license file to the network license manager. Why do I receive License Manager Error -140 when trying to start MATLAB?

License Manager Error -140 is caused by trying to host an a newer license file on an older release of the License Manager. Please update your License Manager by following the instructions in the link below:

How do I update the Network License Manager?

Yes, there have been posts from other people who were not able to use newer versions of MATLAB on client machines until they upgraded the license server.

I do not recall anyone posting indicating that upgrading the license server did not fix the problem. However, if you happened to be using a network.lic file that referred to multiple license servers (for redundancy) then you might need to upgrade them all.
