License Manager Error -16
This error indicates that the path to the MATLAB vendor daemon, 
mlm.exe
, is 
incorrect in your License File 
DAEMON
 line. See “License File” on page 3-4 for an 
example of a 
DAEMON
line. 
License Manager Error -18: License Checkout Failed. License Server Does 
Not Support This Feature.
The most common cause of this error is updating your License File without 
restarting your license manager. Restart your license manager and then try to 
start MATLAB. See “Starting and Stopping the License Manager” on 
page 3-15.
If you get this error on a client system, but not your license server, the License 
File on the client probably needs to be updated. Copy the License File from the 
server onto the your client system (
$MATLAB\bin\win32
).
Here are some other possible solutions to this error:
• Make sure the 
INCREMENT
lines in your 
license.dat
file are exactly as they 
appeared in the original license e-mail you received from The MathWorks. 
• Make sure the 
DAEMON
line in your 
license.dat
file identifies the correct 
license manager daemons, especially if you have multiple MATLAB 
installations on your system.

• Make sure the TCP port number at the end of the 
SERVER
line in your 
license.dat
file is not already being used by another application. Use the 
command 
netstat
to show the status of all ports that are in use. 
On NT systems, run the 
netstat -p tcp
command from 
C:\WINNT\system32
. If the local system appears on the Foreign Address list, 
then the port number listed is being used. Change the port number on the 
SERVER
line to a port that is not being used. FLEXlm has reserved ports in 
the range 
27000
to 
27009
. Restart the license manager after making this 
change.
• Make sure the Host ID or IP Address listed in the commented section in the 
license.dat
file matches the Host ID or IP Address in the 
SERVER
line. If you 
are trying to run the license manager on a different system than the one that 
the license was generated for, you will need to get a new License File from 
The MathWorks.
