Duplexing wizard problem

I unchecked the duplexing wizard option when installing X7 but it was installed anyway. I have tried to uninstall it with the repair tool, but it's still there. The Manual Double-Sided Printing prompt each time I print a multipage job is very annoying. 

 

The printer is a Canon C7010VP with a PS3 Fiery A3200 rip. With other printers which also are duplex I do not get the prompt.

Is there any other way to get rid of this function?
