> If the AV is actually preventing installation with no option to bypass, you may want to wait a couple of days and try again.
On occasion, I've had the installer flagged by our corporate AVs (yes, at one time, IT had 3 (three!) different AV apps installed on our machines). Either I've stuck with an older pre-release build until a new one was released (often within days), or I simply tried again the next day and it installed without complaint.
