QTR-Quadtone RIP

I have an R2400, ordered  Piezography Neutral K7 inkset yesterday, downloaded and  send 
a fee in for the QTR software to my Mac as well.  After the install to the hard drive and 
restart, I see an icon on my Desktop that looks like a piece of paper with the top right 
corner folded down a bit and a picture of my hard drive. Underneath it says 
QuadToneRIP2.43.dmg. In it are all the install components that I originally downloaded. I 
copied the folders named Profiles and Curve Design as well as a PDF named tutorial, an .rtf 
document named QTR license and another item called Diagnosticscript into a seperate 
folder just to be sure they were saved after the install. I tried to load the K7 R2400 folder 
from the profiles folder but received a message saying that a USB connection  is required. I 
don't know if this means USB or USB 2.0 but I am using firewire and so I need to get a new 
cable. 

Presuming that I can get this part to work or at least to install, my question is, where does 
QTR live? I searched my hard drive for QTR and found  several application with QTR in 
their names under something called Eye-One but still can't locate where it is exactly. When 
i connect a USB cable to my 2400 will all become clear or does the software become part 
of photoshop or what? I have never used an RIP, and have always used the ABW driver to 
make prints, which have been really good for the most part but I wanted to try and get the 
best possible prints, hence my interest in the K& inks and QTR.

If anyone can help me understand what I have just downloaded a little better I'd really 
appreciate it.
