Did you quite and re-start Print Tool after running the Install command for the R1800? And then make sure you have the Quad1800 chosen as your printer, not the Epson Stylo Photo 1800.
I can see all of the profiles in the Application/Library//Quad/Quad1800 to confirm they were installed, but simply cannot access them in Print-Tool.
