I'm trying to install a .NET service I wrote. As recommended by MSDN, I'm using InstallUtil. But I have missed how I can set the default service user on the command-line or even in the service itself. Now, when InstallUtil is run, it will display a dialog asking the user for the credentials for a user. I'm trying to integrate the service installation into a larger install and need the service installation to remain silent.
I think I may have found it. In the service itself, the automatically created ServiceProcessInstaller component has a property "Account" which can be set to "LocalService", "LocalSystem", "NetworkService" or "User". It was defaulting to "User" which must have displayed the prompt.
