How to solve rollback install problem [Symantec Endpoint]

Symantec antivirus is not running, please re-install it for user.

Already delete old version and install new version for user.
I have found the problem when tried to re-install this software.
It is not allow to install properly. I need to change some settings in registry as follow:

Find

HKEY_USERS.DEFAULTSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell FoldersAppData
value=%APPDATA%

and change it to

HKEY_USERS.DEFAULTSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell FoldersAppData
value=%USERPROFILE%AppDataRoaming

Install SEP client again.

And found that, still cannot install. So Live update is needed,

Version 3.3 is compatible with this case and Windows 7.
