Similarly, I am unable to download my purchase for tax year 2016. Download help suggests I turn off firewalls/internet security. That seems like tragically bad advice, but even with Norton "paused", I am unable to download (it seems to be trying to download a text file, not an executable).
And, if the order is just a "pre-order", there is no indication in the confirmation e-mail, or in My Downloads, to that effect.
