You're overlooking a chicken-and-egg problem there: your new computer
has no 'tar' to unpack that file.

That assumption is incorrect.

If your in-house network really is so significantly faster than outside
internet that this makes a difference, what you can usefully copy over
from one machine to the other would be setup.exe's package cache
directory tree.  Other than that, there's really no workable short cut
compared to simply running setup.
