Issues Installing Adobe Acrobat PPD

I am trying to add Acrobat 9 PPD to my Indesign Cs6 presets. When I try to follow the following steps I have the presets folder highlighted and when I try to add the folder it goes to another location in my applications. I tried to drag it into the folder and it goes into a sub folder. I feel stupid there has to be an easier way. I am on a MAC 10.7.5 - Thanks
