If no suggestions work have a look for a thread entitled:

HP F380 printer drivers won't install!!

which includes replies posted today.

The F300 series are very bottom of the line and there are many reports
of problems getting them to work, or work consistently, under VISTA.

I posted some last-ditch suggestions today but the real answer is to
get a newer model guaranteed to work under VISTA and tomake sure your
version of VISTA will support the features that are important to you
since Home versions of VISTA donot include the Fax & Scan utility --
you will have to get a third party solution, which may come with the
device you choose.
