I'm sorry, but I don't understand what the above paragraph is trying to
convey.

If you are saying that you downloaded the tar.gz files to a temp directory
and then used the 'd' option to setup to extract them, then that will certainly
work.  That just short circuits the "download from the internet" part of
setup.exe.

If you somehow managed to corrupt the files in downloading them, then, yes,
you will probably get a tar error.

As opposed to what theory?  I don't understand how you would do it any
other way.

There is an md5.sum file in every directory in latest.  setup does not
yet perform a check to make sure that the files it downloads match the
md5 checksum.  That will probably happen eventually.  It does check the
file sizes, though.

ftp, http, or any internet protocol for downloading files from the net
has automatic built in error detection and correction.
