The current U3 package does not support Vista, as you have noted, for
two reasons:

1)  It doesn't change the NPF\Start key in the registry to auto-start
the driver when you run Wireshark for the first time (the standard
Wireshark Windows installer does this, not the WinPcap installer).
This is why you see the "NPF driver isn't running error" when you run
the U3 Wireshark.

(However, if I install WinPcap from the Wireshark Windows Installer
first - and then run the U3 version, it *can* find the interfaces.)

2) The U3 utility program needs elevated privileges on Vista (for
things other than to write the NPF registry key above), which it
doesn't request.

I am working on a resolution for both of these problems and will let
you know when I have something.

Note that the PortableApps version of Wireshark currently has the same
problems on Vista.
