To install Workhorse Whip as a service you will need the InstallUtil.exe that is shipped with the .NET framework.  Look in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727.  The 3.x series does not seems to ship with it.

Install:
cd C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
InstallUtil.exe PATH_TO_BINARY\WorkhorseWhip.exe

net start "Workhorse Whip"


Uninstal
net stop "Workhorse Whip"
cd C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
InstallUtil.exe /u PATH_TO_BINARY\WorkhorseWhip.exe
