After that you keep using your version for as long as you like — you just will not get new updates unless you renew at a discount.

Up to three computers at once, as long as they are yours — for example your home PC, work laptop, and one more. You can reassign the license to a new PC when you replace one, and family members in your household may use it too.

Your license itself never expires, so you can keep using the versions you already have. To receive another 12 months of updates and priority support, renew your existing license using its email address and license key. If your updates have expired, the renewed period starts today.
