Dealing with Problems (Advanced)
When trying to play back video files
using Windows
®
Media Player, the
message [Codec required] appears,
and the file cannot be played back
Some video files use a Codec that is not installed as a standard. In these
cases, if you play back the video file after connecting to the Internet, the Codec
may be downloaded automatically, allowing you to play back the file.
Cannot start a network-used program,
or cannot share files or printers
If you cannot start up a program or share files, this may be because the “Fire-
wall (Windows Firewall)” in the “Windows Security Center” is set to be enabled.
If this function is set to be enabled, damage from viruses and other attacks is
reduced, but some programs and functions cannot be operated.
To use the program or to share files or printers:
You can use programs or other functions without the effects of the Windows
Firewall by registering them as an exception in the Windows Firewall settings (it
is not necessary to disable the Windows Firewall).
Note, however, that if a program is registered as an exception, there is a risk of
damage from viruses or other attacks. Before registering a program as an
exception, confirm the program’s safety with the manufacturer or other reliable
source.
A Select [start] - [Control Panel] - [Security Center] - [Windows Fire-
wall].
B Select [Exceptions].
C To register a network game or other programs as an exception:
Select [Add Program], select the program, and select [OK].
To set access through a specified port as an exception:
Select [Add Port], set the port, and select [OK].
To set a file or printer as an exception:
Add the check mark for [File and Printer Sharing].
D Confirm that there is a check mark for the item to be set as an
exception, and select [OK].
