How can I deactivate MATLAB on a machine I cannot access?

I need to deactivate MATLAB but I cannot access the machine that MATLAB was installed on. Therefore, I am unable to retrieve the deactivation string. How can I deactivate MATLAB without the deactivation string or access to the machine MATLAB was activated on?

If the activated machine is not accessible to obtain the deactivation string or deactivate MATLAB, it is still possible to deactivate. This is done on the MathWorks License Center.
To deactivate MATLAB from the MathWorks License Center:
  1. Go to the MathWorks License Center.
  2. Select the license you want to deactivate.
  3. Select the "Install and Activate" tab.
  4. Under the last column, "Deactivate," click the blue X in the row of the activation you wish to deactivate.
  5. If validation is current, you can click "Deactivate."
  6. If validation is not current, you will be asked for a deactivation string. Ignore this and click the "Manual Deactivation agreement" above the buttons near the bottom of the form.
  7. Click the "Manual Deactivation agreement" above the buttons near the bottom of the form.
  8. Answer the two questions on the page.
  9. Type your name to confirm that you cannot retrieve the deactivation string.
  10. Click "Submit Agreement to Deactivate Software" to complete the deactivation process.

I am sorry to make this thread alive.
How long does it take for the client to deactivate the app? I did some test and followed the steps above on deactivating a license from the licensing manager. I was able to deactivate but on the client machine the app is still activated with the correct license.

"4. Under the last column, "Deactivate," click the blue X in the row of the activation you wish to deactivate."
Do not have this column in my Mathworks-Account . Do I have to be Licence-Administrator to see it?

Hi Abir,
If you only see "Activate to Retrieve License File", the computer may already be deactivated and you can activate your new computer.
Without a license number, its hard to give to you an exact answer. Please contact MathWorks support if you need more assistance.

si no puedo acceder a mi cuenta de administrador de licencias como haría en ese caso?
