Sophos Home Firewall registration consider my license as a 'Temporary Serail Number'

Hello all,

I am trying to register the Home Firewall License. I login in the firewall using web administration and I go in System>Administration then click on 'click here' to register...

Then I enter my serial number, click on 'continue" and dialog bow appears which it mention that : 'Device cannot be activated for a temporary serial number' (flaged in red in the screenshot below).

I request a new home firewall licence - replace my old serial number with the new one (start with V01001....) - but the error is still the same.

Would you please tell me what to do to end up with registration process.

Yours faithfully

  • You cannot replace a serialnumber in SFOS. It is hard in the system. You need to reinstall the firewall. WAs the old serialnumber a trial?

    • Both serial are Sophos Home Firewall licences. This is a new installation but I need to register my old serial to use HA in fact.

      • Hello Tony,

        Thank you for going further in your assistance.

        Both serial number are Sophos Home Firewall. I do not use trials. It has been setup with a new installation on Intel compatible hardware from ISO available on Sophos.

        I am also trying to register from console and I have this message :

        PS : special thanks to Sophos moderator for accepting this add from my previous post.

      • The firewall has been reinstalled after I setup the drive as IDE device and not a SCSI one. Then I was able to register.

        Thanks for patience at Sophos team. All the best.
