Nipper Tool

Hi Experts,

I am trying to download Nipper software to conduct a security audit on my network.

I downloaded the zip file from the following link

- http://www.darknet.org.uk/2008/03/nipper-0115-released-network-device-configuration-security-auditing-tool/

I am unable to locate the nippper.exe file in the folder and when I try to run nipper command the cmd complains as "nipper is not recognized as an internal or external command."

Following is the output of dir to that folder:

 Volume in drive C has no label.
 Volume Serial Number is E449-18B3

 Directory of C:\Users\naziz\Desktop\Nipper\NipperExt
