You see the following error when installing Endpoint Protection 14 on an Windows XP or Server 2003 computer:
Symantec Endpoint Protection 14 can only be installed on Windows Vista / Server 2008 and later. For Windows XP / Server 2003, you must install the legacy 12.1 client package.
Endpoint Protection client 14
Server 2003 R2
Endpoint Protection 14 is not supported on these operating systems as they do not meet the requirements. The Endpoint Protection client 14 will only install on Windows Vista and Windows Server 2008 and later.
Installation of Endpoint Protection 14 clients on Windows XP and Server 2003 is blocked by the installer by design.
By default, new installations of Endpoint Protection Manager 14 do not have the legacy 12.1 client package under Admin > Install Packages to support these operating systems. If the manager is upgraded from a previous version of 12.1, the resulting upgrade will have the required client packages.
Microsoft has discontinued the support of Windows XP and Server 2003 operating systems and is no longer patching or updating these systems. These legacy operating systems are foundational are not capable of supporting the new protection technology and features, or the performance enhancements in Endpoint Protection 14.
Symantec strongly recommends that you replace these machines with a current Microsoft supported operating system for the best security and reliability for today's threat environment.
The Endpoint Protection 14 manager can successfully deploy, administer, and update the legacy version of Endpoint Protection 12.1 clients for these operating systems. This mixture of versions is usually a temporary condition as the endpoints in the organization are upgraded. In the case of Windows XP and Server 2003 endpoints, it may be necessary to use the 12.1 client until the computers running the legacy operating system are retired. Please follow these steps if your environment requires the use of the 12.1 client:
Ensure that TLS communications is enabled for the clients
Click the KB link and follow the steps in article TECH231025 to make sure that TLS is enabled on the Windows XP and Server 2003 clients.
Locate the legacy client packages
The client packages are found in the DVD layout, in the folder SEPM\AdditionalPackages on the media download
SAVLegacy32.info & SAVLegacy32.dat are for 32-bit OS
SAVLegacy64.info & SAVLegacy64.dat are for 64-bit OS
Import the legacy 12.1 client install packages into the Endpoint Protection Manager
Log into the manager console and select the Admin tab
Select Install Packages
Click Add Client Install Package from the Tasks menu
On the Add Client Install Package dialog:
Provide a descriptive name for the installation package in the Specify a name for this package text box
Navigate to the installation package folder (i.e. SEPM\AdditionalPackages\ from the installation media)
Select the .info file associated with installation package (i.e. SAVLegacy32.info)
Click the Select.
Optionally, provide a description of the package in the Description field
Click OK to start the import process
After a successful import, a status window will be displayed
Once the legacy 12.1 client package has been imported, you can use these client packages for deployment to Windows XP and Server 2003 operating systems. For more information about deploying the client see document TECH164327.
