Installation Tips

If you have problems installing the current version of Symantec Endpoint Protection, you should review these possible solutions:
  1. Make sure you have removed all previously installed antivirus software. Ocassionally, an "un-install" does not remove all components, and you may have to uninstall the software manually.
  2. If you experience problems with Microsoft Installer (MSI), you may need to update this Windows component. This component is part of the Windows Operating System, but some older systems may have a version that is too old. You can acquire an update to the installer from Microsoft:
  3. You must be logged in to Windows 2000 or XP as an Administrator or with Administrator permissions before you can complete the installation.

Troubleshooting LiveUpdate

You do not have permission to run LiveUpdate

You will not be able to run the LiveUpdate program unless you have Administrator permissions. If your work group has been setup to NOT have Administrator privileges, your System Administrator can schedule LiveUpdate to run as Administrator. You should make this request from your System Administrator.

LiveUpdate cannnot connect or does not run

You can update your virus definitions using Symantec's Intelligent Updater as an alternative to updating virus definitions using Live Update. Intelligent Updater will update any Symantec product with the latest virus definitions.

You will need to remember to download the virus definitions on a regular basis (weekly, or if you prefer, daily). Be sure to download the correct file for your system. The file to download takes the form YYYYMMDD-###-x86.exe (for example, 20030930-020-x86.exe).
