I have an HP psc 2510, currently installed; communication with PC is
by Wi-Fi.  The problem is that every time a new drive is accessed --
e.g., if I put a DVD in the DVD drive, plug in a digital camera or
memory device to a USB port, etc. -- the installation process seems to
repeat, with distracting pop-up windows ("Installing All-in-one
Series").  How do I fix this?

Try removing the program from your computer. I did a system resotre a
while back and I had a trial version of coldfusion on there. Well when
I restored my computer everything tried installing it again. From
right clicking and so on. So I went into my add remove programs and
deleted it and since then everything has been fine.
