- 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 and so LiveUpdate
- will only download subscription content if a valid subscription is
- found on your machine.
-
- **********************************************************************
- SYSTEM REQUIREMENTS
- **********************************************************************

- * Windows 98/98 SE/Me
- * Windows NT 4.0 Workstation/Server/Enterprise Server/
- Terminal Server (service pack 6 or higher)
- * Windows 2000 Professional/Server/Advanced Server/Data Center
- * Windows XP Home/Professional
- Processor:
- * Pentium 133 Mhz, Pentium 300 Mhz or higher recommended

- versions of Internet Explorer.
-
- **********************************************************************
- WHAT'S NEW?
- **********************************************************************
- 1. Enhanced update selection. The LiveUpdate client is now better able
- to determine which updates it needs to download. The LiveUpdate
- catalog file of available updates can now contain more details about
- the intended target for each update and 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.
-
- 2. 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.
-
- 3. 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 machine. If you wish to
- reinstall LiveUpdate you can do so by following the instructions
- listed below. In addition, when LiveUpdate is uninstalled it will also
- remove any old log files and old configuration files from the machine.
-
- 4. No Windows 95 support. This version of LiveUpdate will no longer
- install on systems running Windows 95.
-
- 5. "No Proxy" option. We have now added an option to tell LiveUpdate
- to not use a Proxy server when retrieving updates via FTP and HTTP.
-
- 6. "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 that 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 which
- Symantec is not liable for.
-
- **********************************************************************
- 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, open the Windows Control Panel and double-
- click the LiveUpdate Control Panel icon. The General tab will be
- displayed by default. Select the Express Mode radio button. You can
- then select how you want LiveUpdate to start. Click the OK button. The
- next time you run LiveUpdate it will run in Express Mode.
-
- To switch back to Interactive Mode, open the Windows Control Panel and
- double-click the LiveUpdate Control Panel icon. The General tab will
- be displayed by default. Select the Interactive Mode radio button.
- Click the OK button. The next time you run LiveUpdate it will run in
- Interactive Mode.
-
- Note that the LiveUpdate Control Panel options are also normally
- available through the 'Configure' button on the first screen of the
- Interactive Mode 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
- only change these options when instructed to do so by a network
- administrator.
-
- You can setup 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 setup 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 username and password information, LiveUpdate will store
- this 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. You should note that 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 easy ways to determine the version of LiveUpdate that
- you have installed.
- 1. Open Windows Explorer and locate the file luall.exe. This is
- usually located in the LiveUpdate client installation folder
- (\Program Files\Symantec\LiveUpdate). Right click on this file and
- select Properties. On the Version tab the File version information
- will be listed.
-
- 2. When you start LiveUpdate, go to the icon in the top right-hand
- corner of the LiveUpdate dialog, click it, 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 folder noted above 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. You can also run LiveUpdate from the folder created under
- the start menu by your Symantec product(s).
- 3. You can go to 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
- **********************************************************************
- Sometimes even the update program needs an update. 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 may require that
- you run LiveUpdate one additional time to complete your session after
- it has finished its update. If this is required, it will tell 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, which use LiveUpdate, install it themselves,
- but if you encounter a problem with LiveUpdate that you or Technical
- Support believe to be the result of an install problem or corrupted
- files, you can reinstall LiveUpdate easily.
-
- To reinstall, 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
-
- Once the file is on your system, double click the icon. You will be
- asked if you wish to install LiveUpdate. Answer yes, and it will
- automatically reinstall.
-
- If you wish to uninstall LiveUpdate, please note that you will no
- longer be able to receive updates to your Symantec products.
-
- To uninstall LiveUpdate:
- 1. Go to the Control Panel.
- 2. Double-click Add/Remove Programs.
- 3. Select LiveUpdate from the list and then click Add/Remove.
-
- To reinstall LiveUpdate at any time, find the LUSETUP.EXE at the above
- URL and simply double-click it.
-
- **********************************************************************
- LIVEUPDATE CONFIGURATION & LOG FILES
- **********************************************************************
- LiveUpdate stores all of its configuration and logging information in
- the following files:
-
- log.liveupdate - Log file
- product.catalog.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 above. In this event LiveUpdate will
- also create a file called 'configuration.log.liveupdate'.
-
- LiveUpdate will also keep backup copies of these 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 machine. The location of this folder is Operating System
- dependent:
-
- Windows 9x
- \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 it's best to search for one of the
- filenames noted above.
-
- **********************************************************************
- USING AOL (America Online)
- **********************************************************************
- Symantec has documentation in our 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
- We primarily use HTTP to download files from the Internet. Our primary
- servers are accessed via the following domains:
- http://liveupdate.symantecliveupdate.com
- http://liveupdate.symantec.com
-
- 2. FTP
- If LiveUpdate is unable to connect via HTTP, it will attempt to use
- the older FTP method automatically. You may need to configure
- LiveUpdate to use an FTP proxy for FTP to work correctly. Our FTP
- servers are accessed via 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.
-
- 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
- downloading LiveUpdate packages. Once you have finished with
- LiveUpdate you can re-enable the "Ad Blocking" software. Alternatively
- you can try to configure your software to allow access to the
- LiveUpdate servers noted in the section above.
-
- 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 machine will free the
- lock on the file. When the file above 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 you should use the 'Configure'
- button on the Interactive mode UI, or run "luall -control" from the
- Start/Run Windows menu.
