Hi Luca,

To successfully use MATLAB on your new laptop after deactivating it from two PCs, follow these steps. Please make sure that MATLAB is deactivated on both PCs where it was previously installed. Although MATLAB allows activation on multiple machines, but typically limits concurrent use. You may need to physically access those PCs or use remote access tools if available. Then, install MATLAB on your new laptop using your MathWorks account. Go to the MathWorks website, log in with your credentials, and navigate to the license center to download MATLAB. Follow the installation prompts carefully. Now, If you encounter errors during activation despite deactivating from previous machines, consider the following:Ensure your new laptop has a stable internet connection during activation. Temporarily disable any firewall or security software that might block MATLAB's activation process. If activation via the internet fails for any random, you can try activating using a license file provided by MathWorks. During this time, if the issue persists, contact MathWorks support to provide tailored assistance. They can help resolve activation errors and ensure your license is properly transferred to the new laptop.

If you follow these steps, you should be able to resolve the activation issue and effectively use MATLAB on your new laptop for work during your holidays. If problems persist, leveraging MathWorks support ensures comprehensive assistance tailored to your specific situation.

How do I contact support? Are there moderators who can intervene directly?

I uninstalled everything...And reinstalled and now I can't use the license anywhere

Hi Luca,

Sorry to hear that you are still experiencing difficulties. To contact support for assistance with license issues or any other concerns, you can reach out to the official support channels provided by the software vendor. Moderators may be available on forums or community platforms to offer direct assistance. Regarding the license problem after reinstalling, ensure that you deactivate the license before uninstalling and then reactivate it after reinstalling to avoid usage conflicts. If the issue persists, contacting support for license activation support is recommended.

I have read and I have already created a mess by deactivating the licenses.. The problem arises when you have to change the PC because it is slow or provide a PC for 30 days (Amazon allows you to try it for this period) and then return it...And when you go back to the old one you can no longer use the license because you have finished the changes

Personally found myself completely unprepared for this information and I'm thinking of switching to Python
