ITunes is telling me "No Disc Recording Software Found"?

Question

Hi,
An error has appeared on my iTunes -- it says when I try to burn a disc, there's no disc recording software found. I uninstalled and reinstalled iTunes. The same message came up, I was expecting my music to be gone as well (I had backed it up on my external drive), and I'm stumped. Can anyone help me figure out how to get the disc recording software onto my computer without me having to drag myself over to Geek Squad?

I'd start with the following document, with one modification. At step 12 after typing GEARAspiWDM press the Enter/Return key once prior to clicking OK. (Pressing Return adds a carriage return in the field and is important.)
