Feel free to reply in this thread if you have any licensing or Myzemax general questions. If you are having troubles with accessing your license or  Myzemax, open a support case or contact your account manager.

Dear all, 

I have send my license from one laptop to other by using an email that is not the one I have in my.zemax, and now I can not receive the license in the second laptop because the Zemax License Manager pops up an error saying 'You are not authorized to use this key'. 

What shall I do to make it works?

Thanks in advance and best regards,

Ana - I have replied to you email request already, but wanted to post here in case anyone else encounters this error. For you, just be sure to login when prompted with the academic email address associated with the license when receiving the transfer.

For others, that error can means that you aren't listed as an 'end user' of the license you are trying to use, transfer or activate. Typically you just need the LIcense Administrator to make you end user of the license. This error is covered is several troubleshooting articles.
