Download message: "the associated helper application does not exist. "

The error message above continues:  “Change the association in your preferences.”  I am trying to download WD Drive Manager (PC) and WD Logo Icon from WD downloads site.  Nothing is downloaded; instead, I get the message above as the reason.  I really do not know what this means.  I’m not having trouble downloading other things.  Windows XP, desktop.

Thank you for your help.

Have you try downloading the file in a diferent computer?
