upgraded from free to internet security

now windows 7 action center doesn’t recognize avast. Also, I can’t seem to find product key after upgrading from avast site.

The product key (license.avastlic file) should have been attached to your email or a link to download it.

You can ask them to Resend avast License http://www.avast.com/resend-license-paid.php, you will need to enter the email that you used when purchasing the license, e.g. the one that the original email with the link was sent.

You could try a clean reinstall of AIS, this may force the Windows 7 action center to recognise avast.
