QTR-Quadtone RIP

This may sound very silly, but I just switched from a PC to a Mac Pro.
 And, of course, I cannot find anything.  I downloaded the newest
version of QTR and cannot for the life of me, after I hit the install
button, find where the program is.  All I find is a subdirectory with
various icons in it but none get me to running QTR.  Can someone point
me in the right direction please?  Thanks.

Mike
