Hi Wayne, eM Client has a strict one license per computer policy, if you were using the demo version of eM Client, you have to obtain a valid license on our website. If the registration notifies you about an existing license, you can retrieve the original license key, using this tool: http://www.emclient.com/lost-activation-key

And use the activation key to activate the product, however note that if you’ve activated the product on another computer, you have to deactivate on the device to use the activation on another computer.

Thank you,
Paul
