I am going to download CARIS HIPS and SIPS, but I can't.
I've checked and Caris Hips and SIPS is not available for public downloading. I located the official website and checked the Products page. On that page, there is a button which indicates that a contact needs to be established with the developers.
Use the following page to read more about it: http://www.caris.com/products/hips-sips/
Note: They also have some free products as well.
