error message: "skindle is not recognized as an internal or external command, ..."

[atomic_monkey]

I'm having a problem and would appreciate some help.

I downloaded Skindle. Then I downloaded 7zip to extract it (it took two steps to extract it -- it went from a .tgz file to a .tar file before I finally got the skindle folder -- not sure if that's normal, but eventually I did find the skindle.exe file).

Anyway, I clicked on skindle.exe, but nothing happens.

That's probably where my problem lies, but I continued anyway. I:

1. downloaded a book to my laptop using Kindle4PC
2. copied that ebook file and dumped it into the same folder on my desktop that contains the skindle.exe file
3. renamed the ebook file book1.azw
4. went to the Windows button on the lower left of the screen, typed "run" in the search window
5. a box popped up that says "open:"
6. I typed into it: 'skindle -i book1.azw -o bookdone.azw' and hit "ok".

I get an error message that says "Windows cannot find 'skindle'":

skindle is not recognized as an internal or external command, operable program or batch file

I ran the built-in Windows diagnostic and it said something about Service Pack 2. I know that Service Pack 2 is a Windows XP thing. I'm using Windows 7 (64 bit). Is that my problem? Is Skindle looking for XP? Does it not work with Windows 7 (64 bit)?

I am not very computer literate, don't know anything about scripts, and don't understand most of the technical stuff in this thread. Scott Blake's posts are the only ones I can follow. So please, please dumb down your responses for me. My feelings will not be hurt.

Thanks.
