QTR-Quadtone RIP

Hi,

I just got a new computer and dutifully installed QTR 2.5.1.8. I have
CS3 and am just learning the new features. I opened a file and got the
image to the point of converting it to the QTR greyscale profile. When
I hit convert to profile, the profiles for QTR weren't there. It has
been so long since I put them on my old computer (and CS2) that I have
forgotten where they are and how I do it. 

Thank you for any ideas. Ifthis is too basic a query, please contact
me off-list.
