Please note that when renewing subscription, there is no need to download and install F-PROT, you only need to update the subscription key.

F-PROT should automatically update the subscription key when the previous subscription expires.

If you want to renew the key right away, you can open the F-PROT software, and click on ´Updates>Renew Subscription>Get new key'

You can also log into the Webshop and access the new subscription key from there:
