Having hunted for these myself recently, I don't know of anywhere to download all volumes of either. However, I did find a few places where one can access certain volumes from each:
In Google Books, I found this file which seemed to be primarily for the New Testament, including a short preface. You will note, however, that the text for much of the Old Testament seems to have been appended for some reason (the wisdom literature and the prophets only, I think) - https://books.google.co.uk/books?id=_XOTP0rctIQC&printsec=frontcover&source=gbs_book_other_versions_r&redir_esc=y
The first volume of the Paris Polyglot, including the text for the Pentateuch and seemingly the front matter for the entire collection, can be found here - https://repository.library.georgetown.edu/handle/10822/712682?show=full
Hope two years isn't too late to be useful. Enjoy!
