Can't Install July CTP - Uninstall the Following Programs?

[Guest]

When I tried to upgrade (which I've done before without a problem), setup
gave me things I had to uninstall before it would continue. I've removed
several applications and now I'm stuch with this:

You must make the following changes before installing Windows
Close Windows installation, go to Programs, and uninstall the following
programs:

Borland Delphi 7.0

The problem is, I don't have Delphi 7.0 installed. I never have. I do have
Delphi 2006 installed, along with many applications that are written in
Delphi. How can I know what is triggering this message and, more
importantly, work past it?

Make an image of the drive and then do a Custom (clean) installation. You
will not be able to recover back to XP without doing a clean install then
anyway.

If this is your production or primary home computer I would not install
Vista on it in any case unless I could install to a blank partition or hard
drive.
