How to Preserve Quicken's auto-update download files

I need to re-install Quicken (2005) because I just rebuilt a system from the OS up. I would like to have a backup of the update file. I know that I can stop the update process between the time that the
update is downloaded from the Quicken site, and the installation of the update. Which directory do i find these files?
I would also like to do this for Quicken 2004 (for backup purposes) and Quicken 2007 (when I buy it)
I Live On Outlook
Thanks (been away for a bit ...)
