In order to get it, please follow these 3 easy steps:
1. open your existing license file in Notepad
2. go to
http://www.avast.com/resend-license.php, fill in the email address you used for purchase, the avast license key which you can find in the license file you opened in step 1, and the verification code
3. hit the "Resend license" button.
In a few moments, you should receive a new license file (called license.avastlic) which you can simply insert to avast v5 (e.g. by double-clicking the file, if avast 5 is already installed on that machine).
Inserting the license key into:
avast! Free Antivirus,
avast! Pro Antivirus and
avast! Internet Security.
