Hello,

My license # is L115250.  I installed Zemax 21.1.1 to my new windows laptop.  Then I transferred this license from my old laptop to this new one.  So I typed in the transfer code.  But I got the error message:

The key service does not work correctly.  please restart your machine and try agian.  If it is not resolved, please contact with Zemax service.

 

So I restarted my laptop, but I got the same error message.  I think the key may be for an older Zemax version and I did not update the license file.  But the installation on the my new laptop is the most updated Zemax version.  Could that be the root cause?

Thank you very much!

 

Cheers,

 

Xi

Hi Xi,

 

I'm sorry to hear that you are having this issue! These errors are typically due to a problem with the licensing software on the machine or a network error. Since restarting the machine and activate again failed, you will need to repare the licensing runtime as explained here. If it still fails, you may need to activate offline. 

 

 

I hope it helps but let us know if not!
