[Installing Dot Net Framework from RunOnceEx getting security warning d]

Hi everybody! Ok i looked around but couldn't find anything resmebling my issue. I have Dot Net Framework 1.1(+servicepack) & 2(+hotfix) and Windows Media Player 10(also +hotfix) installing from RunOnceEx. I know i can do them both from svcpack.ini but this just seemed simpler to setup and maintain. The installations install beautifully, BUT before they commence I am getting a security warning dialog box that asks if I want to run the application(the installation .exe) or not. What confuses me is that i have several other third party apps (Java, Adobe, Symantec, etc) also installing during RunOnceEx that run without this security warning dialog box. Below is the relevent portion of my RunOnceEx

@echo off

SET KEY=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx

REG ADD %KEY% /V TITLE /D "Installing Applications" /f

REG ADD %KEY%\005 /VE /D "Microsoft .NET Framework 1.1" /f

REG ADD %KEY%\005 /V 1 /D "%systemdrive%\Installs\dotnet1_1\DOTNETFX.EXE /Q /C:\"install.exe /Q\"" /f

REG ADD %KEY%\005 /V 2 /D "%systemdrive%\installs\dotnet1_1\KB867460.exe /I /Q" /f

REG ADD %KEY%\010 /VE /D "Microsoft .NET Framework 2.0" /f

REG ADD %KEY%\010 /V 1 /D "%systemdrive%\Installs\dotnet2_0\DOTNETFX.EXE /Q /C:\"install.exe /LANG 1033 /Q\"" /f

REG ADD %KEY%\010 /V 2 /D "%systemdrive%\installs\dotnet2_0\KB917283.exe /Q" /f

REG ADD %KEY%\015 /VE /D "Windows Media Player 10" /f

REG ADD %KEY%\015 /V 1 /D "%systemdrive%\installs\WMP10\MP10Setup.exe /C:\"setup_wm.exe /DisallowSystemRestore /Q:A /R:N\" /Q:A /R:N" /f

REG ADD %KEY%\015 /V 2 /D "%systemdrive%\installs\WMP10\KB917734.exe /Q /O /N /V" /f

Does this strike a chord with anyone? Or am i missing something totally obvious? I just started an unattended installation this morning so i'll try and post a screen shot later this afternoon of the security warning dialog box. Thank you.

[Ad-aware SE answer file?]

First off i want to thank everyone here for this stuff. Without you all my job would be impossible! I'm beginning to feel like a perpetual noobie.

Before i get yelled at I am aware of the silent install method for adaware using '/s' and taskkills posted in these forums. But i was reading a KB article from the Wise about command line switches for software using their packager. It mentioned a '/m filename' switch that can pass variable values to the install. Reminded me of something like the quicktimeinstaller.ini; i was wondering how to go about discovering the variable names used during the adaware SE install to create the answer file. I saw that the installer creates a series of .tmp files in my %userprofile%\local settings\temp directory. I have no way of viewing the contents of those file though. just wondering if this is worth exploring further. the /s + taskkill method does the job but the answer file method seems cleaner. thanks again.

[Quicktime 6: I have searched and searched... but..]

ARGH! I've read these posts about the Quicktime 6.5.X silent installs with the .ini file about a million and one times but for the life of me can't get mine to work. I'm trying to install the free quicktime player through the RunOnceEx.cmd method. I downloaded the full installer from Apple's website.

Here's the line(s) from my RunOnceEx.cmd file:

REG ADD %KEY%\015 /VE /D "QuickTime 6" /f
REG ADD %KEY%\015 /v 1 /D "%systemdrive%\installs\Quicktime\QuickTimeFullInstaller.exe" /f

and here's my QuickTimeFullInstaller.ini file contents

[QTPrefs]
ConnectionSpeed=2147483647
CSMultipleStreams=1

[QTSETUP]
license_option=0
no_dialogs=1
registration_dialog=0
supress_speed_dialog=1
install_qtjava=1
install_qd3d=1
install_quicklaunch_icons=0
install_desktop_icons=0
show_sample=0
show_readme=0
show_programfolder=0
install_qtinfo=0

Could someone please tell what I'm doing wrong?!? My QuickTimeFullInstaller.exe and the QuickTimeFullInstaller.ini files are in the same directory. The RunOnce calls the installer ok, i just can't get it to read the .ini file. I'd prefer not to use the Quicktime Alternative or install Quicktime via itunes. thanks

[disable System Restore during install?]

Does anyone know what nLite does to disable System Restore during the install? More specifically is it just deleting some files, modifying a file or two or is there something i can put into my Winnt'sif or unattend.txt to have System Restore disabled. I ran nLite to remove System Restore and it worked I'm just curious to see what it does. Thanks
