My Passport backup software error message

Hi
I am trying to download WD passport backup software and for some reason I am getting error message ’ A COM + application with the same id already exists. (0 ). I did uninstall the previous downloads and I did not find anything in the Registry to do with WD backup. Can some one help me in this regard Please.
