Thank you for choosing Nero software. Previously, when you bought Nero, you will get a 32-bit code serial number.

Now if you purchase new Nero software in, you will not get serial number anymore. We use completely new Nero Account system to  stores all your Nero products within your account. So you don't have to remember all your serial numbers. With your Nero Account, you can store and keep track of all your purchases and subscriptions after logging into Nero Start on your PC.

Your Nero Account consists of the email address you used when you first signed up or purchased a Nero product. Logging in Nero Account in new Nero Start, it helps you to use your Nero applications and services securely and reliably.

See more information in I bought Nero from website and got the 8-bit code. How can I login and unlock my product after installation.
