MATLAB: Trial license for Matlab Compiler not recognized

license managermatlab coderMATLAB Compilertrial

I opened a service ticket but I was hoping to get started over the weekend and perhaps someone else has run into this and can help.

I have a workstation running R2013a with group licenses for Matlab, Simulink, Signal Processing, Parallel Computing, and Control System toolboxes.

I received a trial license for Matlab Compiler and Coder today. The installation went fine (based on messages) and the Manage License web page shows the trial license has been activated to my machine ID and is good for a month.

But when I try to start compiler or coder I get:

Error using deploytool (line 34) Error: Failed to checkout a MATLAB Compiler license.

I'd appreciate any suggestions.

Thanks, Joe

This seems to be a license issue. Try the following to see if you can even check out the licenses:

[TF errmsg] = license('checkout','compiler')
[TF errmsg] = license('checkout','matlab_coder')

If you see 1 s as output then you should be able to use the tools, if not then you should the error in 'errmsg'. If you are unable to checkout the license, you may have to ask your sys admin or wait till Installation support respond to your service request.

MATLAB: What are the differences between the license.lic, license.dat, network.lic, and license_info.xml license files

There are four different types of license file:

license.lic

For Individual or Designated Computer licenses, this is a standard license file generated from the MathWorks License Center. If this license is automatically generated during installation, it will also contain the hostname, license number and release in the filename.
For Concurrent or Network Named User licenses, this is an unprocessed license file used to install the network license manager. It is also generated on the MathWorks License Center. On network licenses, the license.lic file is *only *used for the installation of the network license manager.

license_info.xml

The license_info.xml file is used for Individual licenses with Login Named User enabled.
This type of license file is common for trial licenses and licenses being used on cloud compute services.
The license_info.xml file contains no license data; rather it instructs MATLAB to connect to MathWorks on launch to authenticate the license.
If a license_info.xml file is in place, you will be prompted to enter your MathWorks Account credentials upon launching MATLAB.

license.dat

The license.dat is a processed license file that is created during the installation of the network license manager on the license server. When the network license manager is installed using the MATLAB installer, the license.dat is placed in the $MATLAB/etc folder (where $MATLAB is the installation directory).
The license.dat contains two additional lines at the top of the file, the SERVER line and the DAEMON line. These lines are generated by the installer and contain information specific to the machine the installer was run on.
The license.dat is used during the installation of MATLAB on network clients.
You can manually convert a license.lic to a license.dat by adding the SERVER and DAEMON lines and changing the file extension from .lic to .dat.
The syntax for the SERVER and DAEMON lines is as follows:

SERVER {hostname} {HostID} 27000
DAEMON MLM {$MATLAB}/etc/MLM

network.lic

The network.lic is created when a license.dat is provided during installation of a network client installation. Similarly, when a network client installation is activated using the MATLAB activation client, the network.lic is placed in the $MATLAB/licenses folder (where $MATLAB is the installation directory).
The network.lic contains two lines, a SERVER line and the USE_SERVER directive.
You can manually convert a license.dat to a network.lic by deleting everything but the first line and replacing it with the USE_SERVER directive.
The network.lic can be used instead of the license.dat for activation of a network client installation.
The network.lic is only used on network client computers.
The syntax for the file is as follows:

SERVER {hostname} {HostID} 27000
USE_SERVER

Please note that with the exception of the license_info.xml license file, these names are conventions, not rules. The exact names and functions of these files may vary depending on your local MATLAB configuration. Any questions related to your specific usage should be directed to your license administrator.

MATLAB: Matlab and Simulink, the same

Simulink needs an additional license. What do you see when you type:

   >> ver

Also try

   >> [TF errmsg] = license('checkout','simulink')
