NmapWin has not been active nor maintained in more than a decade, so users are advised to use the official Zenmap GUI for Nmap instead (https://nmap.org/zenmap/). We are only keeping this NMapWin project live for historical interest. NMapWin is a native Win32 front-end for Nmap (https://nmap.org). It was written by Dr. Jens Vogt.
Outdated and no longer necessary.
This is an obsolete project and there is a replacement for it at nmap.org (ZenGUI)
This is From : http://nmap.org/download.html "Nmapwin has been removed from this download page because it is obsolete. Try Zenmap (included in our installer) instead."
