No, this is a KDE-only launcher - it runs KDE applications, not
'alien' applications like Vuescan.

Now, you're getting closer. But the file 'vuescan' must be
executable. This means that if you look at the file in i.e. Dolphin
you should see something like:
*vuescan 4,4 MiB 24/8-2009 11.25 -rwxr-xr-x root root excutable*
where x means that root, you and others can run the file.
If it isn't, then go to a terminal (konsole) , cd Vuescan and type:
*sudo chmod a+x vuescan* (let them all have x-rights).
If you're still in that directory, you can verify by typing:
*ls -al* (list all files with attributes showing).
If everything is right (the x bit is set), then:
*./vuescan* (the ./ means the current directory).
Now, if Vuescan comes up and runs, of course you'll need an easier
way of launching the program. You could use the menu editor (right-
click on the K icon down left) and fill out the boxes. Or you could
create a link (shortcut) to vuescan by right-clicking somewhere in
your desktop folder and select *create new link to application*

I'm no expert either, but when you think about it the logic behind
the whole rigmarole is beautiful. That's one of the reasons linux
doesn't run viruses. Just imagine Ed Hamrick was an evil person
(which he definitely isn't) and tricked you into something. Well, he
can't, because YOU will decide if Vuescan is allowed to run.

Absolutely not. I just keep it in /opt (which on my system has its
own partition) together with things like Google Chrome, Opera,
Picasa and such non-Kubuntu stuff in order to avoid re-installing
when upgrading to the next Kubuntu version. Just like I keep /home
on its own partition. You're perfectly able to run it from anywhere,
but on a multi-user box I would put Vuescan somewhere outside the
individual users accounts, for example /Vuescan.

That's just the general idea with this list. :-)
