I'm sorry to hear that you are experiencing issues with the activation of MATLAB. Here are some troubleshooting steps you can try:
- Verify that you have an active license: Make sure that you have a valid license for MATLAB and that it has not expired. You can check your license status by logging in to your MathWorks account and checking the license status here.
- Check your internet connection: Make sure that you have a stable internet connection and that there are no firewalls or security settings preventing MATLAB from communicating with the MathWorks activation server. You can try disabling any antivirus or firewall software temporarily to see if that resolves the issue.
- Run MATLAB as an administrator: If you are using Windows, you can try running MATLAB as an administrator by right-clicking on the MATLAB shortcut and selecting "Run as administrator." This can sometimes help to resolve activation issues.
- Delete license files and reactivate: You can try deleting the license files from your computer and then reactivating MATLAB. To do this, go to the "Help" menu in MATLAB and select "Licensing" and then "Manage Licenses." From there, you can select the option to "Deactivate" the license. After deactivating, close MATLAB and delete any license files that may be present in the MATLAB directory. Then, restart MATLAB and follow the prompts to reactivate the license.
If none of these steps resolve the issue with MATLAB activation, I recommend reaching out to MathWorks support for further assistance. They can provide you with more specific guidance based on your particular situation.
