Matlab License Manager Error
Walda Caesar
I ran ./activate_matlab.sh and activated it through the license file AND login into MathWorks online. I deleted the installation .lic in R2020a/license/ and created a new one. I tried creating a license file with every mac address I could find. Nothing works. I keep getting this error. Only once I managed to use Matlab, which was right after installing it. Then after the first time closing it I'm I have been stuck on this error for 2 days. Please help me.
License Manager Error Messages
After a successful installation, you may encounter problems starting MATLAB. Many of these problems have their root in the license manager used by the MathWorks products, FLEXlm.

It can also be helpful to view the FLEXlm log file, lmlog.txt, in the $MATLAB\flexlm directory. To get more information about a FLEXlm license manager problem, see the FLEXlm End User Manual, available in PDF format in $MATLAB\flexlm\enduser.pdf or go to the GLOBEtrotter Software, Inc. Web site, www.globetrotter.com.
- Note You can also go to the support page on the MathWorks Web site, www.mathworks.com, and find information about a particular license manager error by searching the solution database by error number. For example, to find information about License Manager Error -15, enter "License Manager Error -15" in the search engine.
License Manager Error -5: License Checkout Failed. No Such Feature Exists.
This message usually indicates that you are trying to use a product for which you are not licensed. Check your License File to see if you are licensed to use this product.
If you are licensed for this product, this error may be the result of having extra carriage returns in your License File. To avoid this, make sure that each line begins with either #, SERVER, DAEMON, or INCREMENT.
This error may also be the result of an incorrect system date. If your system date is set before the date that your license was made, you will get this error. See License Manager Error -10: Feature Has Expired to learn how to reset the system date.
License Manager Error -8: Invalid (Inconsistent) License Key
This error message typically indicates that your License File, $MATLAB\flexlm\license.dat, has been corrupted. This can happen if the License File was edited or if an e-mail program inserted extraneous tabs or carriage returns in the INCREMENT lines.
One way to check for extraneous tabs and carriage returns is to open your License File in a text editor and view all nonprinting characters. Remove all the tab characters and all carriage returns that are not at the end of a line.
License Manager Error -9: Invalid Host. License Checkout Failed.
If you get this error on a system running an individually licensed MATLAB, make sure you are running MATLAB on the same system it was installed on. The MathWorks locks a license to a particular system.
You can also get this error if you replaced your hard drive or changed the partition on an existing hard drive. To remedy this situation, rerun the installer. At Step 5: Select the Products You Want to Install, click on the More Options... button on the Product List dialog box and select the Update license option. This option updates your license without requiring that you reinstall MATLAB.
Check the expiration date on each of the INCREMENT lines in your License File. If the dates in the license file have already passed, contact the Customer Service department at The MathWorks (through the Web or through e-mail at ser...@mathworks.com). When contacting The Mathworks, include your License Number and the Host ID of your license server.
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.
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.
License Manager Error -13: No SERVER Line in License File
This indicates that there is no SERVER line in the License File. This line should be added by the installer during the installation process.
To remedy this problem, run the installer again or manually edit the License File, $MATLAB\flexlm\license.dat, adding the SERVER line. See License File for information about the format and contents of the SERVER line.
License Manager Error -14: Cannot Find SERVER Hostname in Network Database
If this error occurs on a client system, check to make sure that the hostname on the SERVER line in the license.dat file on your client system matches the hostname on the SERVER line in your license.dat file on your license server. Edit the SERVER line in the client license.dat file, if necessary.
License Manager Error -15: Cannot Connect to License Server
This error message can have several causes but the most common cause is that the license manager isn't running on your license server.
Verify that both the license manager daemon and the vendor daemon processes, lmgrd and mlm, are running. You can check this via the Task Manager, which can be accessed by pressing the Ctrl+Alt+Delete key sequence. Run these commands on the system on which your license manager is running.
License Manager Error -16
This error indicates that the path to the MATLAB vendor daemon, mlm.exe, is incorrect in your License File DAEMON line. See License File for an example of a DAEMON line.
License Manager Error -18: License Checkout Failed. License Server Does Not Support This Feature.
The most common cause of this error is updating your License File without restarting your license manager. Restart your license manager and then try to start MATLAB. See Starting and Stopping the License Manager.
If you get this error on a client system, but not your license server, the License File on the client probably needs to be updated. Copy the License File from the server onto the your client system ($MATLAB\bin\win32).
License Manager Error -21: 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 FLEXlm included with Release 13. Release 13 License Files will not work with the older FLEXlm versions.
License Manager Error -25: License Server Does Not Support This Version of This Feature
This error indicates that you are trying to run MATLAB 6.5 with an old license. You must update your license.dat file with your new license passcodes.
This table lists a typical cause of this error with possible solutions.
Possible Problem
Resolution
You are not listed as a user in your options file.
Check your options file and make sure your username is on the INCLUDE line for the product you are trying to use.
On UNIX computers, the installer creates the options file, named $MATLAB\flexlm\MLM.opt.
License Manager Error -83: FLEXlm Version of Client Newer Than Server
This error message usually indicates that the version of the license manager on the client system is newer than the license manager on the server system. When MATLAB starts, the license file is pointing to the wrong version of the license manager.
To correct the problem, change the path of the DAEMON line in your license.dat file. For a UNIX server, the DAEMON line for all license files should resemble this sample (the pathname of your daemon will be different).
License Manager Error -88: License Checkout Failed
This error indicates that your system clock has been set incorrectly. Check that your system date and time are correct. To learn how to change the system date, see License Manager Error -10: Feature Has Expired.
License Manager Error -96: Server Node is Down or Not Responding
This error can occur if you are running DHCP (to obtain a dynamically assigned IP address) on your license server. MATLAB cannot connect with the License Manager because it uses TCP/IP protocols for communication and your IP address is changing.
