License Manager Error -11: License Checkout Failed. Invalid Date Format 
in License File. 
This error indicates that the start date or the expiration date in the License 
File is invalid. This can happen if the expiration dates in the License File have 
been changed. 
You can also get this error if the space character between the number of users 
field and the 20 digit encryption code in the 
INCREMENT
line is missing. 
Compare the 
INCREMENT
lines in your license file with the 
INCREMENT
lines in 
your original license e-mail. They must be exactly the same. 
This error can also occur if the 
SERVER
and 
DAEMON
lines are missing from the 
license.dat
file. The installer adds these lines to the License File as part of 
the installation process. 
License Manager Error -12: License Checkout Failed. Invalid Return Data 
from License Server. 
This error can be caused by your network setup. When the license manager 
tries to connect to the server, the DNS Server does not find it because it does 
not add the domain name suffix into the search.

located in 
$MATLAB\bin\win32
, to have the fully qualified name of the 
server.

Restart the license manager on the server. (See “Starting and Stopping the 
License Manager” on page 3-15.)
If only some of the clients in your concurrent installation are having this 
problem, edit the TCP/IP Hosts file on your client systems:
