It means that it could find code that should do the installing.

Hello Joachim,

Check that u use installutil.exe from the latest installed FW folder "WINDOWS\Microsoft.NET\Framework\v2.0.50727\"
and not the 1.1

You need to have an Installer class in your service in order for Installutil
to be able to "install it". Look at a sample service for the code you need.
