Dear Behzad, 

You have to first transfer the license from your old machine to new machine. You can do this by going to configure licence (search in window bar) and then chose transfer licence option under send license. 

Once done, then use the transfer code received via your registered email in the recieve license option on the configure licence window of your new machine.

Remember, the transfer is only possible once a month so be very careful. 

You might want to try copying the entire ZEMAX folder (all contents -- it will be quite a lot) from your original computer to the new one into the same folder location.  When you plug the key into the new computer, it may think it’s already installed and bring the license code with it.  I don’t know if that will actually work, but there’s no harm in trying.

I think this post is now solved since my colleague sent you a licence code on Friday.

Thanks all for your kindly help. 

appreciated so much.

Regards,

Behzad
