Upgrade to Symantec Endpoint Protection Manager (SEPM) 14 MP2  fails due to the side-by-side configuration error, the upgrade of the SEPM rolls back because it fails to install LiveUpdate properly.

In the log %TEMP%\SEPM_Inst.log the error message just before the line "Return value : 3" is something like:

Generate Activation Context failed for "C:\PROGRA~2\Symantec\LIVEUP~1\LUCOMS~1.EXE".  Syntax error in manifest or policy file.

1. C:\PROGRA~2\Symantec\LIVEUP~1\Microsoft.VC90.CRT.MANIFEST. component
2. C:\PROGRA~2\Symantec\LIVEUP~1\Microsoft.VC90.CRT.MANIFEST.
