Why do I receive License Manager Error -68?

I receive the error below when trying to start MATLAB:

License Manager Error -68: license borrow not enabled.

[MathWorks Support Team]

License Manager Error -68 indicates that the license borrowing feature is not enabled.

To resolve this issue:

1. Go to the folder where the network license manager is installed

C:\Program Files\MATLAB\R20***\etc\win64

2. Open "lmtools.exe"

3. Click on the "Borrow" tab

4. Choose the option "Do not borrow anymore today"

5. Start MATLAB again

NOTE:

This error can also occur when borrowing is attempted using a license that is not borrow enabled.

Be sure the license.dat on the license server has license borrowing enabled, and the client either has a SERVER USE_SERVER type license.dat file or the borrow enabled file from the license manager.
