Problems With Unattended Install Thunderbird 2

[greggkelly]

Hi,

I'm trying to include Thunderbird 2 in an unattended install of XP through a RIS server. I tested the command "Thunderbird Setup 2.0.0.16.exe -ms" in the command prompt on my own computer and it works fine; it fully installs. But when I added this command under the [GuiRunOnce] in the .sif file, it didn't work as smoothly during a network install. When the installation comes to that command the "Open File - Security Warning Do you want to run this file? blah blah" warning comes up and requires user input to continue. Is there anyway to disable this or a better way to silently install Thunderbird?

Thanks,

Gregg
