There's not a download page for Haptek characters. You can download the full-body demo or the Haptek SDK, both of which contain the full-body .htr files. You can also visit any page which has Haptek characters, and dig them out of your temporary internet files afterwards. If you do this, rename them to take the notations like [1] out of the file names (i.e., if you retrieve a full-body[1].htr, rename it to full-body.htr)
