AVG 7.5 Technical FAQ » License number
It is possible that the AVG license number was not entered correctly. Please compare the license key you have entered with the one you have received from us. However, we recommend you to use the Copy & Paste method to insert your license number correctly, as this will avoid mistakes.
The license number is sent to the e-mail address used in the registration form immediately after the registration process. If you didn't receive any e-mail, there are several possible reasons:
- the e-mail has not been sent, the registration process has not completed correctly
Please try to register once again on this page - you are using some spam filter
The e-mail has been probably filtered by an anti-spam control on your computer or on the mail server. Please contact your system administrator to solve this. - e-mail address has not been entered correctly
Your e-mail address has not been entered correctly into the registration form so it is not possible to deliver the e-mail. In this case please contact our sales department using this sales support form. Thank you.
If the end of the license period is approaching, and you have received your new license number, please follow these steps to extend the license period:
- launch the AVG Control Center (double-click on the AVG icon in the systray)
- choose the Activate AVG option in the Information menu
