This is a fake download of Adept PDF Converter Kit. In both the automated wizard driven download and the manual download, the process continues until about 90%, then the download stops and breaks. There is an interrupted network error. There was never any intention by the software developer to allow users to download this software. What a phony giveaway.
Given my own experience with the invitation AND the download, I tend to agree with the above. Just another way to get you to buy it.
