Don't remember where the post was, but someone had a problem after installing Nmap on their system. When they clicked on the desktop icon for Nmap, a command prompt window appear briefly, then disappeared. You can fix this by right clicking the shortcut (make sure it is the shortcut on the desktop and not the nmap.exe from the nmap folder), selecting properties and placing the following in the Target field:

C:\WINDOWS\system32\cmd.exe "C:\Program Files\Nmap\nmap.exe"

Since the program it launches is cmd.exe first, the icon will change to a cmd icon. So if you want to be fancy, click on the "Change Icon..." button and select C:\Program Files\Nmap\nmap.exe.

Presto... you're up and running.

Hope this helps,
Don

Correct me if I'm wrong, but the Windows GUI for Nmap was nmapwin, and that hasn't been updated or supported for quite some time.

So it's now strictly a command line utility, and I think Fyodor likes it that way.

What were you using and when did you install it?
