It is not possible to update your system if your service and support agreement has expired.
The expiration date can be found in your Service and Support Agreement contract or in Help --> About in the CapaInstaller Console.
If you try to update with an expired license you will get the following message, informing you that you must contact CapaSystems A/S to renew the license.
To proceed, dismiss the message by pressing OK, then select Update License.
Now simply input the newly aquired license key and continue.
