Matlab Reactivate License
Maral Mende
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.

MATLAB is a high-level language and interactive environment that enables you to perform computationally intensive tasks faster than with traditional programming languages such as C, C++, and Fortran. It integrates mathematical computing, visualization, and a powerful language to provide a flexible environment for technical computing. The open architecture makes it easy to use MATLAB and its companion products to explore data, create algorithms, and create custom tools that provide early insights and competitive advantages.
NJIT MATLAB license is renewed annually. If you are getting a warning about the expiration of the license please, click on the message that pops up to update the license, or follow the instructions below to reactivate MATLAB.
If the installation has already expired, you will be prompted to activate when attempting to launch MATLAB. As long as the activation finishes successfully it will roll over to the new license file once the old one expires. You might continue to see the expiration warning in MATLAB until the old file expires.
The software has a 30-day grace period after the official end date of the MATLAB license on August 1. Users who do not reactivate after August 30 will be prompted to reactivate once they launch the program.
When the option Prompt when editing driversthat do not exist is selected, if you open the MATLAB InstrumentDriver Editor while specifying a driver file that does not exist,you get a prompt asking if you want to create a new driver file.
If you select Do not show this promptagain, the corresponding check box in the Preferences dialogbox is cleared, in which case the MATLAB Instrument Driver Editorcreates new driver files without prompting. To reactivate the prompt,select the option on the Preferences dialog box.
When the option Prompt when editing drivertests that do not exist is selected, if you open the MATLABInstrument Driver Testing Tool while specifying a driver test filethat does not exist, you get a prompt asking if you want to createa new test file.
If you select Do not show this promptagain, the corresponding check box in the Preferences dialogbox is cleared, in which case the MATLAB Instrument Driver TestingTool creates new driver test files without prompting. To reactivatethe prompt, check the option on the Preferences dialog box.
Set the default size for these character arrays in the Preferencesdialog box to ensure that they are large enough to accommodate anystring returned to them by any device object functions. You can reducethe default character array size to avoid unnecessary memory usage,as long as they are still large enough to accommodate any expectedstrings.
Once an account is created, it can be used for downloading, updating, and licensing MATLAB on the user's Mac and Windows and Linux workstations. And, through the same account, the user can use MATLAB Mobile (a free app) on an iPhone, iPad, or Android device.
The campus site license expires in December each year, so users renew their licenses annually around that time. Choose "Licensing" from MATLAB's Help menu and choose Update Current License. If not updated by the end of December, a user must reactivate the license by running the computer's Activate MATLAB utility, or take the opportunity to upgrade to the latest version by downloading it from the personal MathWorks account.
With contributions from the College of Engineering and other colleges, ITS has obtained a University-wide software license for a number of MathWorks products that are now available to U-M students at no cost. MATLAB, Simulink, and 26 other MathWorks products and toolkits are included. The software and license keys are available now for download by U-M students only. Details on how to download the software can be found at this ITS website. Be sure you register with your @umich.edu email address. Once activated, the license key will expire each year and qualified students will need to reactivate it annually. Note that this software is not for use by faculty or staff, who still need to contact ITS Software Licensing and Distribution for license codes.

Matlab Online Log in with a Dartmouth-associated Matlab account (see below) and log in to Matlab at at -online.html This is a lightweight version of Matlab that runs in modern browsers such as Google Chrome.
NEW! Dartmouth has licensed Matlab Academy, a series of self-paced online classes. The classes cover all aspects of Matlab.
You can access Matlab Academy at You will need to login to your Mathworks account to access the classes. If you don't already have one, you can create an account. Be sure to use your Dartmouth email address.
Products, click "Select all" checkbox to UNselect all, then check MATLAB (note, installer is 3.8GB or greater as of version 2021A) and any required toolboxes. Caution: some toolboxes dramatically increase space needed (GB of space with some toolboxes)
On the Product Selection screen, install Matlab choose the software you need. Depending on the software selections, Matlab installation may require as much as 30 GB of space. If you are a student in a class using Matlab, you may get guidance on what toolboxes are necessary.
When the installation is completed, the Matlab software will be activated. You have a stand-alone license so that you can run Matlab without being connected to the internet. The license will expire each year on June 30th and you will need to reactivate it after Dartmouth renews its site license each June. Other license options include Student, Campus and Concurrent.
Toolboxes: Commonly used toolboxes include: Curve Fitting, Image Processing, Optimization, Parallel Computing, Statistics and Machine Learning. If you are in doubt about which toolboxes to install, you can install just Matlab and rerun the installer at a later time to install additional toolboxes.
Open Matlab, and click the "Home" tab at the top of the application. On the "Home" tab, click the "Help" button with the question mark icon on it at the top right of the Matlab window. From the menu that drops down, go to Licensing->Update Current Licenses. You must be connected to the Internet in order to update the license.
