Software Deployment

I'm working on packaging TurboTax 2011. Here is what I have found so far.

Intuit offers a (InstallShield) Setup.exe for each language of their software. The setup.exe (not the MSI) writes to the TTConfig.ini in C:\ProgramData\Intuit Canada\##2011 to save some of the preferences used by the gui. The TTConfig.ini must be configured or the install won't launch post install. Install command is like below.
C:\FILES\Source_ENG\setup.exe /s /v"TRANSFORMS=C:\FILES\Source_ENG\TurboTax2011.mst /liwear c:\logs\TurboTax2011.log /qn"

Written at install and managed by the Setup.exe:
WebAccess=1
HelpSurvey=0

Written at registration:
UTID="randomly written number"
ActCode0="randomly written number"
InstCode0="randomly written number"
NSAKey="Registration code for your license after registration"

Written at first launch after answering the questions or changing the options:
KeepUpToDate=0
RegistrationShown=1

My questions is, I am trying to find a way to disable updates completely and maybe hide the buttons. So far, I've tried to use AdminStudio's Repackage to capture the changes which is how I found the other ini changes, but I can't seem to find the others.
