Custom Installs and Vista

[Guest burn033@gmail.com]

I have a question about customizing Windows application installs than

installing them on Windows Vista. For example I customize the install

for Thunderbird to have all the default values set so when we setup a

mail account we do not need to change any options. Now the problem

that I am having is after I install Thunderbird on a vista computer

each time they run Thunderbird it prompts a security certification

issue. Now there is an option to remember this setting but even

though I put the check box in that each time I run Thunderbird it

still prompts asking if they want to run it. Is there anyway that I

can add this program to a list somewhere so it won't ask them if they

want to run it or is there something that I can do to the install so

this doesn't happen?
