If you are using Bitdefender 2013 (Antivirus Plus, Internet Security, Total Security) you can upgrade, free of charge, to the Bitdefender 2014 version by:
1.
Installing it directly over the older version with the
installer provided. During the installation process you will receive a
notification informing you that a previous version was detected. Click
Yes to uninstall it, reboot the computer, then proceed the installation.
If the older version was registered, Bitdefender 2014 will "remember" the respective license key.
2.
Removing the older version, restarting your computer
and installing the new version. The product settings of your previous
version will not be saved. Please use this upgrade method only if the
first option fails.
