problem making an addon for MSSE

[DeltaCom]

I'm trying to make a silent switchless installer for Microsoft Security Essentials

i'm using

;The comment below contains SFX script commands

Setup=setup.exe /s /runwgacheck /o
TempMode
Silent=1
Overwrite=1

and it will work on a PC, but not in an install when XP installs.

Any idea as to why?

Maybe its not svcpack compatible, may need to be installed via runonceex or wpi

well it works fine in here

but i extracted the setup.exe <<maybe that what stop the svcpack

but i did a lot of tests and they are fine

and also i don't add that /o i used the taskkill to terminate
