Questions about NortonLifeLock 360 Deluxe

After buying the product from Digitec, I cannot enter the product key. Error message: "Before you can use the Norton subscription with this new key, we need additional information for registration. Perform the registration at norton.com/setup." there it always wants to sell me a subscription and charge my credit card. however, I have already paid, I just need to be able to enter the ProdKey. How does this work now?

It looks like there are subscription versions and non-subscription versions of Norton. With the latter, you would not have to enter any payment data (credit card) when registering/activating before installing. With the subscription versions, the opposite is true and the subscription is automatically renewed. This is irrelevant for card holders, as the data can apparently be deleted from the account afterwards. Unfortunately, I don't have a credit card and would like to buy Norton 360 or any other antivirus that doesn't require a card. Why is this not stated by the providers? it's impossible ....

I will install the product later. Question, I assume that this product is activated after installation and not from the date of purchase?

ist es ein download code

Declared as full version. Is it necessary to enter a credit card for activation? Should be unnecessary. If it is: Return must be possible due to incorrect declaration

Can this software be activated without entering a credit card?

can you use this product without a credit card or not? some say credit card or paypal and others say nothing. What is the difference? I don't have a credit card and don't want one. greetings

Do I need to provide a credit card during installation or activation?

Can you be protected for 5 years with the 5 licences? If you only have one device and then redeem the next licence at the end of the previous one?

What is the difference between this product (Norton 360 Deluxe) and Norton Security Deluxe + WiFI Privacy. There seems to be a secure VPN in both. Thank you
