OK, you certainly don't have to accept any alternative suggested.  But it
does sound to me like you're adding additional requirements that you didn't
previously state.  In other words, if using "setup*.exe" once manually to
populate a download directory (or simply creating a package mirror) is
enough to get you everything you need, you can certainly verify that it's
possible to install from that directory using the script you've created.
That should be all you need for at least one iteration of your unattended
installs.  If you plan to alter this process or the download directory on
a regular basis, then certainly there is some overhead in verifying the
script still works as you intend.  No argument here.
