I agree with the first post. A GUI is definately needed. I have been looking for a simple, free program with a GUI that does nothing more then list all the duplicate programs and where they are located. That way you can select which program to delete, leaving the one you want where you want it. Everything would be under your control and unexpected out comes, would be minimized. The ability to drag the dupes to the trash from the list would be great also. This would cut down on the navigation time to grab the program you want for deletion.
