That's exactly what I was saying. Wubi,exe as downloaded from the wubi-installer
website requires a web install, but the CD does not. My point was that he may
not get the same error if he tries the CD approach. He said that he downloaded
wubi.exe which led me to be that he was not using the CD.

I am not familiar with Vista as I don't use it. I have not seen this error
reported before. It is a shot in the dark, but worth a try, if he has the CD.
