I downloaded from the email with my license key. The download went fine but it won't allow the installer to open.

Exactly what I am saying. There is not option to run anyway. It just tells me that I am protected. I wonder if it's because I deleted the McAfee first?

Trying to download installer and can't get past the Windows Defender. Turned off AV and Firewall plus all notifications but still can't get through. Can't delete Defender either.
