Navigate to  ...\All Users\Application Data\Symantec\LiveUpdate folder.
Open the settings.liveupdate file

The following settings must be changed:

PREFERENCES\INTERNET_CONNECT_TIMEOUT=<value in seconds>
PREFERENCES\INTERNET_READ_DATA_TIMEOUT=<value in seconds>

The following is an example of how this setting would appear for a 30-second time-out value:

PREFERENCES\INTERNET_CONNECT_TIMEOUT=30
PREFERENCES\INTERNET_READ_DATA_TIMEOUT=30

CHANGE THE VALUE TO 300

Dear Mr. Kumar,

thanks for your reply.

i found a dozen of such files, do i need to change all of them?
after changing such a file, while saving it shows "access denied" even after remove the read-only attribute.

please refer to attached

regards,

open control pannel
select liveupdate
make it to interactive
start
run
here select only few components to download like only AV and AS
check if that completes

You have to edit the settings file(Last one which is do not having any number.)

Copy the settings.liveupdate file and paste the file on the desktop

After that make changes to the file and save it on desktop.

Then replace the back to the original location.
