I am trying to install Symantec Endpoint Protection version 12 on Windows 7 64 bit, and during the installation it keeps failing and rolling back. I checked the log file, and the error code I'm getting is 1603.

A co-worker found the solution. The installation of Symantec Endpoint Protection (SEP) client fails and rolls back around the point of registering with LiveUpdate


In the registry,


HKEY_USERS.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\AppData value=%APPDATA%

and change it to

HKEY_USERS.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\AppData value=%USERPROFILE%\AppData\Roaming

Install SEP client again.
