An update for the System Center Endpoint Protection 2012 Client was released today. It installed successfully on Windows clients (Windows 8.1) throughout the organisation but fails on servers (Windows Server 2008 R2, Windows Server 2012 R2).
The Event Viewer reports the following error.
Installation Failure: Windows failed to install the following update with error 0x80070643: Update for System Center Endpoint Protection 2012 Client - 220.127.116.11 (KB3106514).
Technet has an article describing this issue, although it relates to an older update (from April, 2012). It does however give us a few ways to troubleshoot the issue.
1. Make sure the server does not have any pending reboots. PowerShell-script can be found here.
2. Remove any existing security programs
3. Ensure that the Windows Installer service is running
4. If you’re getting updates through Configuration Manager, try clearing the cache. If that does not help run the SCEP setup manually.
