QTR-Quadtone RIP

Hello all!  I'm hoping someone here can help me with an 
install/uninstall problem with QTR 2.4.2 on a G4 Mac running Tiger 
10.4.8.  I bought QTR some time back to use the Create ICC programs and 
hadn't looked at the rest of the program until now.  I wanted to try my 
hand at profiling and creating curves and have run into a problem 
locating all of QTRs elements.  

I admit to moving things around a bit willy nilly looking at and using 
various portions of the package and probably deleting a few as well in 
desktop cleanups. I think I started with 2.4.1 as well.  At this point 
when I run either the install package trying to regroup the program by 
installing over the existing installation or running the uninstall 
package to clean up and start over I consistently get a: There were 
errors installing the software, flag.  

Any suggestions for cleaning up and starting over?   Thanks in advance, 
Robert.
