There seems to be something broken… It’s supposed to download properly, as long as you actually use the the link from the axantum site. Direct links should behave as you describe. However, when I try it now, it seems that it’s not working as intended.
We’ll have to investigate. It’s supposed to work, but we have previous reports of it intermittently not working as expected.
To download the 1.7 version of AxCrypt from http://www.axantum.com you have to do so from the site directly, *not* from a direct link. (Technically, the referrer of the request must be http://www.axantum.com, in practice this means you should browse the web site and click the link on the web site in your browser).
