How to Preserve Quicken's auto-update download files

Hi,

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 ...)
