I have downloaded Avast ! 4 Home and it's up and running on one user profile (there are 3 on the computer, all with administrator rights). I tried to use the same license key for the other profiles, but the message "invalid license key" popped up. I therefore made two new registrations (using two different e-mails), one for each remaining profile, and tried to enter the new license keys. Those numbers also appear to be invalid according to the pop upp messages. What should I do?
PS. There's no avast ball icon near the clock on the two profiles I'm having trouble with. I tried to enter the license key by accessing Avast through a shortcut icon on the desktop.
