QTR-Quadtone RIP

I read some of the previous threads on this.  One challenge is that I
am running a 9880, which doesn't seem to be a profile listed in QTR. 
Also I tried following some of the other advice about looking in
system preferences > printers & fax, but it doesn't show up there.

I've installed 2.5.2 several times, installed the patch... and it's
there, because I even tried installing 2.5.1 and it said there is a
newer version installed.  But I can't find QTR anywhere on the computer.  

Help!  :-\

Thanks,
