may fail because of incompat-
ibilities with other applica-
tions.

exit the other applications and try starting the
installer (AVNavigator_e_ver_*_*.exe) again.

tor. First set the IP address on the receiver,
then set the same address in AVNavigator
(page 66).
Network connections could be
restricted due to the computer’s
network settings, security set-
tings, etc.

settings, etc.
