Hi there, i'm trying to install nmap for windows OS from the insecure.org website and have read the instructions on how to do it but i can't, can anyone give me a step by step guide please? (i'm sure there's only three of four steps)

I've dowloaded nmap and also winpcap (i've installed that) but i've got to go into MSDOS and i get lost at the part where the insecure.org site starts talking about changing and creating directories because i don't know how to use MS-DOS.

I'm just confused because the instructions seem easy enough but when it says create the directory for nmap i wonder why, because surely it's already in one isn't it?

I have some of the tools and have read quite a few things now, just need a little more knowledge of windows and DOS and my newbie phase should be over........
