How do I register a trial version?
If you have installed a trial version, you may only use it for a limited period of time. To continue using Bitdefender after the trial period expires, you must register your product with a license key.
Note: even if you have paid for a Bitdefender product, a trial version is initially installed. A valid license key can be subsequently used to register it during the configuration steps that follow the installation or any time later.
To register Bitdefender, follow these steps:
Open the Bitdefender window.
A link that indicates the number of days left on your license appears at the bottom of the Bitdefender window. Click this link to open the registration window.
Enter the license key and click Register Now.
If you do not have a license key, click the link provided in the window to visit a web page from where you can purchase one.
Wait until the registration process is completed and close the window.
