I downloaded Avast free home edition yesterday and just this afternoon got the license key in the email.
After copying the license key from the email I went to “insert license key” in Avast and pasted the license key in the pop-up window. When I click “ok” I get a pop-up that says "license key is not a valid License key!.
If I try “Register Now” after filling out the information I get a message that says “the system cannot find the file specified”
At the moment I Avast is useless and I can’t do anything with it.
