Why do I get error 379 while attempting to activate or log in?

During activation or log in of MATLAB, I receive the error 379 "No licenses were found". How do I resolve this?

If you are looking to purchase a license or start a trial, view the link below.

https://www.mathworks.com/store/

This error is caused due to the use of an incorrect Activation Key within the installer including

• If you are using an Activation Key that is invalid. Please use the correct Activation Key in order to activate MATLAB.
  • Unless you are trying to link your MathWorks account to a new license, you do not need an Activation Key. If you are not tied to any licenses, please either contact your organization to be tied to a license or purchase one.

• If you are using an Activation Key for a license that is Login Named User (LNU) only.
• If you are trying to log into an LNU prompt with an account that does not have an LNU license.

Login Named User (LNU) is a portable license option that verifies license rights over the internet and requires users to log into their MathWorks Account each time they start MATLAB. As such, LNU requires an uninterrupted internet connection.

Please contact Mathworks Support. The volunteers who answer questions here do not have access to the sales or license information.

Constancio Pinto: It has something to do with comet C/2019 Y4 (ATLAS) breaking up into pieces. Mathworks did not anticipate that, so you will have to contact them and work with them to activate your MATLAB.

The volunteers who answer questions here do not have access to the licensing database.

If you purchased your MATLAB directly from Mathworks then you need to contact Mathworks Support.

If your license is being provided by your university or workplace, then you need to contact them. If you do not know who to contact them Mathworks Support can give you the contact information for your location.

The volunteers do not have any activation keys to give out.

If your license is from a university, contact the university. If your license is from an organization that you work for, then contact the support staff of the organization. If you purchased your license directly from Mathworks, then contact Mathworks Support for installation assistance.

@Herilaza RANDRIANARISON

The volunteers who answer questions here do not have access to the license database. Also, the license terms say that we can only make available the licenses that we do have to other people in the same organization that we are in -- so if I had a spare license, I would not be permitted to let you use it.

You need to contact the place you got your license from -- your university or your employer, or Mathworks Sales if you bought from Mathworks.

@Esam Abraham

See my repliy to Herilaza, directly above. The volunteers still cannot help you in this matter.

hola.tengo matlab r2012a y me pide una activation key.tenia entendido que este software era gratuito

[Walter Roberson]

In R2012a, serial numbers were still used instead of Activation Keys. You should contact Mathworks Support if you need assistance in finding your serial number.
