[Air-L] Deduce Qualitative Analysis software?

Hi all I'm doing a project that involves (amongst other things) comparing data from emails and I am looking into software that might help me with my analysis, which will involve qualitative and a small amount of quantitative research, though some of the quantitative stuff is so basic I can do it in Outlook! I had Deduce recommended to me, but I can't find a link to it anywhere - does anyone know how I can find it? Would Nvivo also be useful - and does anyone know of any other tools that I can utilise?
