I followed the steps here to make my existing WCF service (already working fine as console application) be Windows Service as well, on my Windows 7 machine which is also my development machine.
No matter what I tried, when doing the last step of using installutil, I'm getting the following message in the command line:
Exception occurred while initializing the installation:
System.BadImageFormatException: Could not load file or assembly 'file:///[path here]' or one of its dependencies.
An attempt was made to load a program with an incorrect format..
I have my console application main class inherit from ServiceBase and implement OnStart and OnEnd methods.
I have added ProjectInstaller class inheriting from System.Configuration.Install.Installer marked with [RunInstaller(true)] attribute and with the code they supplied in the constructor.
What I already tried that is not mentioned in the above article?
Also, I don't get any log file even when specifying it with /LogFile=myLog.txt.
Any ideas are welcome, thanks.

A windows service is what you need. WCF is a communications library, and unless you plan to communicate with your application via a client, you don't need it. Your problem is related to activation, and keeping your code active in the background is what windows services do.
Windows Communication Foundation (WCF) is a framework for building service-oriented applications. Using WCF, you can send data as asynchronous messages from one service endpoint to another. A service endpoint can be part of a continuously available service hosted by IIS, or it can be a service hosted in an application.
A . svc file contains a WCF-specific processing directive (@ServiceHost) that allows the WCF hosting infrastructure to activate hosted services in response to incoming messages. The most common syntax for a . svc file is in the following statement.
There are three types of hosting environments for WCF services: IIS, WAS, and self-hosting. The term “self-hosting” refers to any application that provides its own code to initialize the hosting environment. This includes console, Windows Forms, WPF, and managed Windows services.
That smells like a 32-/64-bit problem.
Is your machine 64-bit Windows 7 by any chance?? Does your service somehow reference something 32-bit , like an old COM component or something??
You might need to compile your stuff with the x86 platform in Visual Studio to get it to work properly...
