license renewal

Renewal is automatic unless you cancel, so if you have a payment method it will keep right on billing you.

Good evening.
If your contract has already expired, you should have a new, annual contract.
In some cases, it may not be possible to contract successfully due to the influence of the previous contract history. In that case, it seems necessary to contact the sales representative for consultation.

Not sure what you are asking.

The Adobe Subscription model has an Auto Renewal system, as long as the payment method is the same, where on the day your subscription end it Automatically get Renewed.

I have no idea what or if PC World is selling one year subscriptions, Paid in full for one year, of Adobe software.

For some plans Adobe itself offers a one time payment for a yearly subscription. If it were me I would buy directly from Adobe and not PC World.
