Error sending data (12007) in Windows XP

Dear sirs,
a customer of mine receives the following error when he tries to activate the workbook:
Error sending data (12007): the server name or address could not be resolved.

He uses Windows XP. My activation url is https.
Is there any solution?



HTTPS may be the reason. Your server certificate probably requires a TLS protocol not available on Windows XP. You should try to offer manual activation to this customer.

Ok. Is it possible to deactivate a manual activation if the user in the future wants to move the application on another pc? (hardware lock)


XLS Padlock has no automated deactivation feature yet. But it’s on our road-map.
You’ll have to trust that customer for moving from their PC to another one.
