Scripting

I have a problem with deploy the new Symantec Endpoint Protection 12.1.3, not with the installation of the client but with an internet explorer add-on.

There is a new IE Add-on "Symantec Vulnerability Protection" for Insight-Lookup. The first start of the IE9 after the installation there is an pop-up with this quesiton:

But i don't want that the user see this after the first start of IE9. It should be enabled by dedault. 

So I made an Active Setup after the installation with this commands:

:: Active Setup for Usersettings

:ActiveSetup 

if not exist "%inst%\Active Setup" md "%inst%\Active Setup"

if not exist "%inst%\Active Setup\%AppName%" md "%inst%\Active Setup\%AppName%"

copy /y "%~dp0ie9_AddOnEnable.reg" "%inst%\Active Setup\%AppName%\ie9_AddOnEnable.reg" >>"%LogFile%"

copy /y "%~dp0UserInstall.cmd" "%inst%\Active Setup\%AppName%\UserInstall.cmd" >>"%LogFile%"

reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\%AppName%" /v "StubPath" /t REG_SZ /d "\"%inst%\Active Setup\%AppName%\UserInstall.cmd\"" /f

in the UserInstall.cmd i make a 

regedit /s "%~dp0ie9_AddOnEnable.reg"

ie9_AddOnEnable.reg:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Ext\Settings\{6D53EC84-6AAE-4787-AEEE-F4628F01010C}]

"Flags"=dword:00000000

This Reg enables the Add-On. But anyway there comes the pop-up above with the question if you want to enable or disable it.

How can I hide this message, any ideas?
