A Troubleshooting
License Manager Error -18: License Checkout Failed. License
Server Does Not Support This Feature
This error tjrpically indicates that you have updated your License File without
restarting the license manager. Restart the license manager and try to start
MATLAB again.
If you get this error on the client, but not the server, the license. dat file on
the client probably needs to be updated.
Make sure that the INCREMENT line in your License File exactly matches the
INCREMENT line in the license information you received from The MathWorks.
License Manager Error -21: License Checkout Failed. License
File Does Not Support This Version
If you are getting this error on your license server, make sure you have
installed the version of FLEXnet included with the release you are trying
to install. Older FLEXnet versions will not work with the License Files for
new releases.
If you have updated an existing license.dat file with new passcodes, you
still need to install the latest version of FLEXnet included with the release.
If you are getting this error on one of your client systems and not on the license
server, make sure the License File on the client is in the following format.
SERVER host hostname port_num
USE_SERVER
The SERVER line in the client system License File should be the same as the
SERVER line found in the License File on the license server.
