Problem Solution
You did not choose to allow
access when the security alert
dialog box appeared during
either the standard installation,
BRAdmin Light installation, or
when printing
If you did not choose to accept the security alert dialog box, the firewall function of
your security software may be rejecting access. Some security software might
block access without showing a security alert dialog box. To allow access, see the
instructions of your security software or contact the manufacturer.
