If you do not purchase Nero Platinum Suite directly from Nero.com, but via e.g. Amazon, eBay, Software Store, etc., you will get the 32-bit activation code in the purchased software package.
After installation, you need to firstly register your Nero Account directly in Nero Start.
Launch Nero Start, enter any of your email address in the first screen, and Nero Start will check to see if a Nero Account is already registered with that email address. If no such Nero Account exists, Nero Start will help you register a new Nero Account.
During registration, your password for the new Nero Account will be sent to the email address you provided. Enter the password in Nero Start to complete the registration of your Nero Account.
You can also skip the registration during the first startup in Nero Start and do it later in the account settings.
To do this, click the account settings button in the upper right corner of Nero Start, and click “Register” to create a Nero Account.
In the Nero Account Registration window, enter your e-mail address, click the "Resend my password" link, and your password will be sent to the e-mail address you provided. Enter your password and click the “Register” button to complete the creation of your new Nero Account.
