                           ABOUT LIVEUPDATE
**********************************************************************
LiveUpdate is the Symantec technology that permits an installed
Symantec product to connect to a Symantec server over the Internet to
check for program and other updates such as virus definitions and URL
lists.

When updates are available, LiveUpdate downloads them to your computer
and installs them, keeping your Symantec software up to date. All
updates that are downloaded with this version of LiveUpdate are
checked for a valid digital signature.

Certain types of content may require a subscription. LiveUpdate
will only download subscription content if a valid subscription is
found on your machine.

**********************************************************************

**********************************************************************
                              WHAT'S NEW?
**********************************************************************
New Enterprise features
1. Support for non-Symantec content. LiveUpdate will now install
content that has been signed by a certificate that can be verified
against the local certificate store.

2. Location profiles. LiveUpdate can now be configured to communicate
with multiple sets of servers. With this feature enabled, LiveUpdate
can retrieve updates from Symantec servers, or from Central LiveUpdate
servers on the intranet.

3. Uninstall prevention. It is now possible to configure LiveUpdate so
that is cannot be uninstalled from the computer.

4. Update prevention. It is now possible to configure LiveUpdate so
that it cannot be upgraded to a later version.

New general features
1. Last run date and time. The LiveUpdate Options menu, available in 
the top left corner of the LiveUpdate dialog, now has an option to
report the last time that LiveUpdate was run, and how the last
LiveUpdate session ended.

2. Single log file. LiveUpdate will now log to a single log file. New
log entries appear at the bottom of the file.

3. Enhanced update selection. The LiveUpdate client is now better able
to determine which updates need to be downloaded. The LiveUpdate
catalog file of available updates can now contain more details about
the intended target for each update, and LiveUpdate will only download
an update if it meets the target criteria. 

For example, an update may only be required if a user is running on a
specific service pack of an operating system, or if they have a
particular version of a component installed on their machine. This
evaluation is performed by the LiveUpdate client, and no information
is ever sent to Symantec.

4. Enhanced Error Support. Most LiveUpdate error messages now
include links to more comprehensive error details and resolutions.
The Enhanced Error Support web site links can be accessed by clicking
on the area around the "Click here for more information" text on error
dialogs and messages.

5. Uninstall support and cleanup. Some Symantec products may now
remove LiveUpdate from your machine if LiveUpdate determines that no
other Symantec products remain on the computer. If you wish to
reinstall LiveUpdate, you can do so by following the instructions
under the heading Updating LiveUpdate. In addition, when LiveUpdate is
uninstalled it will also remove old log files and old configuration
files from the computer.

6. No Windows 95 support. This version of LiveUpdate will no longer
install on computers running Windows 95.

7. "No Proxy" option. An option has been added to tell LiveUpdate
to not use a Proxy server when retrieving updates via FTP and HTTP.

8. "Do not manage my Dial-up Networking connections" option. This
option should be used if you do not want LiveUpdate to manage your
Dial-up Networking connection to the Internet. 

Note: When you select this option, LiveUpdate will not automatically
close any Dial-up Networking connections that it may have created to
connect to the Internet. This may result in unexpected phone charges
for which Symantec is not liable.

**********************************************************************
        SWITCHING BETWEEN INTERACTIVE MODE AND EXPRESS MODE
**********************************************************************
There is an option in the LiveUpdate Control Panel to allow users to
switch between Interactive Mode and Express Mode. This switch is
available on the 'General' tab of the LiveUpdate Control Panel applet.

To switch to Express Mode

1. Open the Windows Control Panel and double-click the LiveUpdate
Control Panel icon. The General tab will be displayed by default.
2. Select the Express Mode radio button. 
3. Select how you want LiveUpdate to start. 
4. Click the OK button. 
The next time LiveUpdate runs, it will run in Express Mode.

To switch back to Interactive Mode
1. Open the Windows Control Panel and double-click the LiveUpdate
Control Panel icon. The General tab will be displayed by default.
2. Select the Interactive Mode radio button.
3. Click the OK button.
The next time LiveUpdate runs, it will run in Interactive Mode.

Note: The LiveUpdate Control Panel options are also available through
the 'Configure' option in the LiveUpdate 'Options' menu on the user
interface.

**********************************************************************
                              PROXY SERVERS
**********************************************************************
Most Internet users don't need to configure their computers to use a
proxy server, however some ISPs and companies require you to connect
to the Internet through a proxy server. You can configure LiveUpdate
to use a Proxy via the LiveUpdate Control Panel applet.

Note: If you do not know what a proxy server is, it may be best to
change these options only when instructed to do so by a network
administrator.

You can set up LiveUpdate to use HTTP or FTP Proxy servers by
selecting the appropriate tab in the Control Panel, and then choosing
the second radio button to customize the settings.

By default, LiveUpdate will use the same proxy server settings that
you have set up for use with Internet Explorer.

Note: LiveUpdate uses HTTP for file transfers by default, however it
will fail over to FTP if it is unable to communicate via HTTP.

If your proxy server requires authorization for outside access, you
can also enter a user name and password for HTTP proxy servers.

If you have any difficulty configuring your proxy settings, contact
your network administrator for assistance.  Each network is different,
so only they can help you with this step.

Important security consideration:
---------------------------------
When provided with usernames and passwords, LiveUpdate will store
this information in its settings file in encrypted form. However,
when this information is sent to a proxy server, it is sent in an
encoded, but unencrypted form. It is sometimes possible to capture
data packets on the Internet, or on your LAN, and therefore it's 
possible that your password data may be viewed by others during
transmission to the proxy server. If you have any concerns, please
contact your network administrator.

**********************************************************************
                  VERSION & DIGITAL SIGNATURE INFORMATION
**********************************************************************
There are two ways to determine the version of LiveUpdate that
you have installed.

1. Open Windows Explorer and locate the file luall.exe. This file is
usually located in the LiveUpdate client installation folder
(\Program Files\Symantec\LiveUpdate). Right-click on LUAll.exe, and
then select Properties. Click the Version tab to see the File version
information.

2. Run LiveUpdate, click on Options in the top left-hand
corner of the LiveUpdate dialog, and then select
"About LiveUpdate". The full product version is listed.

You may also right-click on any of the LiveUpdate executable files
(*.exe, *.dll) in the LiveUpdate folder and select the "Digital
Signatures" tab to view the Symantec Digital Signature on the files.

**********************************************************************
                           RUNNING LIVEUPDATE
**********************************************************************
There are several ways to run LiveUpdate.

1. Through your Symantec product. Most Symantec products which use
LiveUpdate offer a LiveUpdate button.

2. Run LiveUpdate from the folder created under
the Start menu by your Symantec product(s).

3. Open a command prompt and run LUAll.exe, or create a
shortcut to this program on your desktop
(\Program Files\Symantec\LiveUpdate\LUAll.exe).

Note: Some product updates may only be retrieved by selecting the
LiveUpdate option from within that product (option 1).

**********************************************************************
                          UPDATING LIVEUPDATE
**********************************************************************
LiveUpdate occasionally needs to be updated. LiveUpdate will
automatically check to see if there are any available updates to
itself each time it is run.  It should update itself transparently
(without any extra input), but in certain rare cases, it may require
that you run LiveUpdate one additional time to complete your session
after it has finished its update.  If this is required, LiveUpdate
will prompt you.

Updates to LiveUpdate are also posted to the URL below:
http://www.symantec.com/techsupp/files/lu/lu.html

**********************************************************************
                   INSTALLING/UNINSTALLING LIVEUPDATE
**********************************************************************
All Symantec products that use LiveUpdate include it as part of the
product installation.

If you encounter a problem with LiveUpdate that you or Technical
Support believe to be the result of an installation problem, or
Corrupted files, you can reinstall LiveUpdate.

To reinstall LiveUpdate
1. Locate LUSETUP.EXE on your computer or on the CD-ROM
containing your Symantec product. 

You may also download the latest version from the Internet at:

http://www.symantec.com/techsupp/files/lu/lu.html

2. Double-click LUSETUP.EXE.  
You will be prompted if you wish to install LiveUpdate.
 
3. Click Yes. 
The LiveUpdate program will automatically reinstall.

If you wish to uninstall LiveUpdate, note that you will no
longer be able to receive updates to your Symantec products.

To uninstall LiveUpdate:
1. Open the Control Panel.
2. Double-click Add/Remove Programs.
3. Select LiveUpdate from the list, and then click Add/Remove.

**********************************************************************
		LIVEUPDATE CONFIGURATION & LOG FILES
**********************************************************************
LiveUpdate stores all of its configuration and logging information in
the following files:

log.liveupdate			- Log file
product.inventory.liveupdate	- List of installed Symantec products
settings.liveupdate		- Configuration settings

If LiveUpdate cannot find its configuration files, it will recreate
default versions of the files. In this event, LiveUpdate will
also create a file called configuration.log.liveupdate.

LiveUpdate will keep backup copies of the product and settings files
by adding a number to the beginning of the filename. The higher the
number, the older the file.

These files are normally located in the Application Data folder on
your computer. The location of this folder is Operating System
dependent:

Windows 98/98SE/Me
\windows\all users\application data\Symantec\liveupdate

Windows NT/2K/XP
\Documents & Settings\all users\application data\Symantec\liveupdate
or
\Windows\profiles\all users\application data\Symantec\liveupdate

Some other Windows XP systems
\Documents & Settings\all users.windows\application
 data\Symantec\liveupdate

If you cannot find this folder, search for one of the 
filenames noted above.

**********************************************************************
                      USING AOL (America Online)
**********************************************************************
Symantec has documentation in the Symantec online knowledgebase that
can assist you in using LiveUpdate with America Online.  Please go to
the following URL to review this information:

http://service1.symantec.com/SUPPORT/sharedtech.nsf/docid/19982515512

An important consideration in configuring LiveUpdate to work with AOL
is to first make sure you are using a recent version of the AOL
software.

Note: Symantec is not liable for any phone charges incurred when
making this dial up connection. Don't forget to close your Internet
connection when you have completed your LiveUpdate session.

**********************************************************************
                        TECHNICAL INFORMATION
**********************************************************************
LiveUpdate uses three possible methods, or transports, for retrieving
updates and installing them.

1.  HTTP
HTTP is the primary method used to download files from the Internet.  
The primary Symantec update servers are accessed using the following
domains:
http://liveupdate.symantecliveupdate.com
http://liveupdate.symantec.com

2.  FTP
If LiveUpdate is unable to connect using HTTP, it will automatically
attempt to use the older FTP method.  You may need to configure
LiveUpdate to use an FTP proxy for FTP to work correctly.  Our FTP
servers are accessed using the following domain:
ftp://update.symantec.com

3.  LAN (Local Area Network)
Corporate customers may wish to create their own internal LiveUpdate
servers to ease bandwidth usage.  More information about the LAN
transport is available from within the LiveUpdate Administration
Utility.

NOTE: If LiveUpdate finds the LAN transport file (s32luhl1.dll) in the
same directory that it is being run from, it will search for a LAN
entry in its settings file and use that transport instead on the FTP
and HTTP transports.

**********************************************************************
                            KNOWN ISSUES
**********************************************************************
1. Password Security:  Please see the Proxy Servers section above for
more details on known issues with transmission of password
information.

2. The Automatic LiveUpdate component may be configured to
check for virus definition updates in the background.  Normally,
LiveUpdate will only do this when it detects an open Internet
connection.  However, some devices, dialup routers for example, can be
configured to create an Internet connection when they detect this
activity.  Users should note that this could result in unexpected
connection charges.  In addition, automatic LiveUpdate may behave
differently with different versions of the AOL connection software.
We recommend that you review the "USING AOL" section above.

NOTE: ISDN on-demand Internet access and Automatic LiveUpdate.
ISDN charges are generally higher than standard analog phone line
charges, so users of these systems are asked to pay particular
attention to this issue.

3. Some "Ad Blocking" software products may deny LiveUpdate access to
the file servers from which it downloads updates. If you are using
this type of software you should disable it if you notice problems
when downloading LiveUpdate packages. Once you have completed a
LiveUpdate session, you can re-enable the "Ad Blocking" software.
Alternatively, you can try to configure your software to allow access
to the LiveUpdate servers listed in the Technical Information section.

4. If you use defragmentation software and you use the Automatic
LiveUpdate feature, you should note that this may cause the
defragmentation software to restart every time Automatic LiveUpdate
checks for an Internet connection (usually every 5 minutes).  If you
notice this behavior while defragmenting your hard drive, it is
suggested that you pause the task scheduler until defragmentation has
completed.

5. Some 'Zip' utilities may intercept the updates that are being
downloaded by LiveUpdate and cause problems while LiveUpdate is
trying to uncompress these files.

You can work around these problems by temporarily turning off this
feature of your Zip utility when you are running LiveUpdate.  For more
information, visit the Symantec support website at
http://www.symantec.com/techsupp/

6. Some combinations of Windows NT 4.0 running on Intel Pentium 4
processors cause LiveUpdate to display a LU6003 error.  To resolve
this issue you should install/re-install NT 4.0 Service Pack 6 or
higher.

7. On some Windows NT/2K systems, the LiveUpdate control panel icon
may not work properly. This may be because the LiveUpdate installer
was unable to upgrade the old control panel functions. To resolve this
problem, try restarting your computer and deleting the file
S32LUCP1.DLL from the \windows\system32 folder. 

Note that the operating system will lock this file if you try to open
the control panel before deleting the file. Restarting the computer
will unlock the file. When the S32LUCP1.DLL file is removed, the new
control panel functions will be available.

8. On 64bit Itanium systems there will be no LiveUpdate Control Panel
applet.  To access this functionality, run "luall -control"
from the Start/Run Windows menu.  In addition, you may also select the
"Show x86 control panel" option from within the control panel on 64bit
Windows systems.

9. Some Symantec product update patches may update the version number
of the product it is updating.  As a result, when targeting custom
content updates for these products, precautions should be taken to
account for this.  Custom content which is targeted for a registered
product of one particular version will no longer be retrieved by
LiveUpdate if the version number changes.

10. Some of the help text within the ISP tab in the LiveUpdate control
panel may be truncated due to a bug in Microsoft's HTML help.  If this
occurs, please try applying all the critical and recommended updates
which are made available through Microsoft's Windows Update web site.

11. You cannot use the "-temphost" command-line feature to point
LiveUpdate at a CD-ROM device. This is due to filename length
limitations with the CDFS file system.

12. When using custom content, it is not recommended that you use the
LUAdmin download folder to host custom content. LUA can be configured
to remove unused content, and this will result in the custom content
file being deleted. You may avoid this issue by not using the
"Cleanup Download Directory" option.

13. With Location Profiles, it is now possible to configure LiveUpdate
to access different servers for content. LiveUpdate records the names
of the files it has downloaded, and it will not try to download the
same file again if it does not have a more recent date and time stamp.
As a result, if you have a file sharing the same name on two different
servers, LiveUpdate will only download the newer file.
