How to install KillDomino?

I try to just execute the exe file, but I got error message, failed to initialise, any help is appreciated.

Subject: Use NSD - included with Notes/Domino client

When you need to kill Notes because its no longer responding, you can issue an NSD from the command line. You can also create a batch file to do that…

C:\Program Files\lotus\notes\nsd.exe -kill
