After applying Microsoft update KB2781197 to a Windows 8 computer, the Symantec Endpoint Protection (SEP) client installer fails.


The following lines are from the SEP_INST.log generated from a failed installation attempt:


(SERVER)     MSI (s) (04:18) [08:56:49:093]: Executing op: CustomActionSchedule(Action=ShowServiceProgress,ActionType=3073,Source=BinaryData,Target=ShowServiceProgress,CustomActionData={3771A34D-2132-48EA-A486-D62ECDF9D553};SOFTWARE\Symantec\Symantec Endpoint Protection;Executing install script via service;)

(UNKNOWN)     ScriptGen: ShowServiceProgress() calling WaitForSingleObject(scriptStarted) ... 
(UNKNOWN)     ScriptGen: ShowServiceProgress() WaitForSingleObject(scriptStarted) returned WAIT_OBJECT_0 
(UNKNOWN)     ScriptGen: ShowServiceProgress() script execution failed.
(UNKNOWN)     ScriptGen: ShowServiceProgress() reset script failure event.
(UNKNOWN)     ScriptGen: ShowServiceProgress() is returning an error (so close to the end!) 
(UNKNOWN)     CustomAction ShowServiceProgress returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)


This problem is fixed in Symantec Endpoint Protection 12.1 Release Update 3 (12.1 RU3). For information on how to obtain the latest build of Symantec Endpoint Protection, read ‘Obtaining the latest version of Symantec Endpoint Protection or Symantec Network Access Control

If it is not immediately possible to upgrade, you can work around this problem using one of the following:
