How do you use "Addzer0"?

[Adren]

I'm using a guide and it says to put Addzer0 in the folder with the iso. I did that. Then it tells me to type "Addzer0 Input.iso output.iso 12210” so my command line looks like this:

C:\Documents and Setting\Adren>Addzer0 Input.iso output.iso 12210

(Though the number is different, mines upwards of 600k)

And I get some annoying error I get whenever I type something in command... blah blah not a command...

How do I use this?
