Having Applescript call an external Installer to install Out

I have a question I’d like to ask about calling or executing applications from an Appplescript script.

Say I want to install Outlook 2001 on my mac from a script, how would I have to go about it? Is it just making a Call to a location that the installer is at?
BTW the Installer is already packaged using Install Maker.

Thanks for all your help so far.

You can use a script to launch the installer. If there are dialogs for user input, this won’t bypass them - the installer will behave as if its icon was double-clicked by the user.

tell application “Finder” to open file “path:to:installer”
