In otherwords, is the version instance just considered the YEAR number of MATLAB or does version compatability include the letter designation as well? Can a client 2018 "B" installation checkout license features from a MATHWORKS license server that has ONLY the 2018 "A" level licenses for checkout?
MATLAB: Will the license file verions 2018″A” support / allow a 2018″B” client to check out licenses
license version year only or included letter designation

To improve license mobility, license borrowing can be enabled for network licenses. License borrowing allows users to run MATLAB and other MathWorks products on computers that do not have a continuous connection to the license server. This article will provide information on:
- How to Enable License Borrowing
- Limitations of License Borrowing
- Interoperability with Previous Releases
How to Enable License Borrowing
To enable license borrowing, a License Administrator must contact MathWorks Installation and Licensing Support:
Once it is enabled, the license file on the license server must updated to include borrowing, the instructions for this are in the link below:
After you have implemented the borrow-enabled license file on the server, MATLAB users can enable the borrowing interface in MATLAB. For instructions on how to do this, please see the following support article:
How do I use the License Borrowing UI to borrow licenses from within MATLAB (as of R2009b or later)?

Limitations of License Borrowing
- Borrowing is only available for Commercial and Non-Degree Granting Education licenses.
- Borrowing is available for Network Concurrent and Network Named User licenses.
- Borrowing is not available for Polyspace R2019a and later.
- To enable borrowing for a Network Named User license, an Installation and Licensing Support Technician must first verify that borrowing is supported in your environment.
- Licenses can be borrowed for a maximum of 30 days.
- Borrowing is only available for MATLAB R14 or later.
- Borrowing is only available for license servers running FLEXnet v9.2 or later.
- Network Named User licenses require FLEXnet v11.6.1 or later.
- MathWorks products must be installed on client systems. This configuration is called local client access in the MathWorks install documentation.
Interoperability with Previous Releases
When using a License File that supports license borrowing, you can only use license borrowing with Release 14 products or later. You can run Release 13 products but you cannot check out a borrowed license for these products. You cannot check out or run Release 12 (and earlier) products.
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 $MATLAB is the installation directory).
- The license.dat contains two additional lines at the top of the file, the SERVER line and the DAEMON line. These lines are generated by the installer and contain information specific to the machine the installer was run on.
- The license.dat is used during the installation of MATLAB on network clients.
- You can manually convert a license.lic to a license.dat by adding the SERVER and DAEMON lines and changing the file extension from .lic to .dat.
- The syntax for the SERVER and DAEMON lines is as follows:
SERVER {hostname} {HostID} 27000DAEMON MLM {$MATLAB}/etc/MLMnetwork.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} 27000USE_SERVERPlease 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.
