QTR-Quadtone RIP

Hello,

I have some strange problems when installing/removing QTR 2.4.2 on a  
Mac PPC G5 dual core OS X 10.4.7.
Any advice to solve them are welcome.

Here is the story:
First I installed QTR on a G4 OS X 10.3.9 and everything seemed to  
work as it should, profiles etc.
However, I had to move the printer to the G5 before I could evaluate  
QTR.
The G4 and the G5 are on the same network.
Installed QTR and the profiles on the G5, printer connected and  
switched on.
But the profiles didn't show up, I have confirmed that they are at  
the right place.
Decided to remove and reinstall but the Remover doesn't work it keeps  
saying "can't continue because there is nothing to install".
Neither the Installer or the Remover ask for Admin.
At one time I added the shared quadprinter from the G4 but removed it.
After that "quadtone rip" wan't dissapear from the drop down menu in  
the Print dialog box.
I have tried, several times with removing and adding printer in the  
Print Center, restarting, restore disk permissions, disconnect the G5  
from the network, moved all xxxxxprinter.plist from the user/prefs  
folder. I have also tried to use US English as system language, helps  
sometimes with other problems.
Every time I add the printer I get two "quadtone rip" in the drop  
down menu and the profiles never show up.

Any ideas what to do?
How do I get rid of the second "quadtone rip" and how do I find the  
profiles?

Best and TIA
Hans
