Lots of IFs -- in my order of preference:

IF the program has a command-line option to download without a 'button
push' (ie, --download <list of files>), use that.  IF is doesn't, ask
that such be added if you can.  (Utility programs ought to have such
options just so they can be used programmatically without operator
present, just like you want to do.)

IF you can start download with keys instead of just mouse, and if
program takes keypresses through generic standard input functions
(like C getchar()) rather than specific getkey function, start it at
the other end of a pipe.

IF program has COM interface, get PythonWin stuff and use that.

IF you can find (or write or modify open-source code to make) a
mouse-click simulator program thats responds to dynamic input via
stdin (rather than only responding to prewritten script read as
startup), use that.
