Hi,

For starters your attempting to copy a windows .exe file to your
usr/local/bin ??? the windows .exe will not work under linux!

To keep your Linux system safe, you (the user) only have read/write
access to your home directory and /tmp so if you really need to copy
anything to anywhere else you are going to have to do this as the system
administration account (root)

If you are using the GNOME desktop, then press [alt + F2] and type "gksu
nautilus" and then you can achieve what you are setting out to do...
However, be warned when you are using nautilus as root you can do damage
to your install if you're not 100% certain what you are doing! (just be
careful and don't delete anything system related!)

[off topic]
That device that you are attempting to program, does it appear as its
own comm. port? (/dev/ttyU*)
