Jeff,

As I told another user, you guys are the first in these forums to
use the download and install routine. Even us beta testers downloaded
an ISO and burnt it to a DVD. So, I don't know of anyone who has
tested this type of install. I'm sorry.

Don't expect any Microsoft employee to answer your questions
here. This is really a user support forum, with barely any official
presence from Microsoft.

Call Microsoft.

Take care,

Michael
