Currently TS hosts the newest 7.x shareware version of X-Setup Pro with time-limited trial.
It would be nice to give people the freeware alternative of X-Setup Pro 6.6 available here: http://www.internet-magazin.de/downloads/cm/dtt/file.php?areaid=79&fileid=912&sfiles=1

Hey I tried to add the free version you linked, but all I got was a page with an old version of X-Setup Pro.

The old version, is the free version. It is still newer than Windows XP, so all the tweaks apply and work just fine.
