As of 28 Feb, the only file you can download from anywhere, it seems, is the shareware version (v7, xqdcxsp-setup-en.zip, 3,422,883 bytes). Granted, it's only $8, and well worth it, but it ain't free anymore.

Strange that I couldn't find any links to download previous versions, which are free, in spite of prior assurances from the X-Setup creators that the 6.x versions would remain available after 7.0 was released!
