Castle Windsor can't find installers in assemblies

Question

I have code in my global.axax:

protected void Application_Start()
{
    WindsorContainer = new WindsorContainer();
    WindsorContainer.Install(FromAssembly.InDirectory(new AssemblyFilter(AppDomain.CurrentDomain.RelativeSearchPath)));
    ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(WindsorContainer.Kernel));
//...
}

When I debug global.asax, code FromAssembly.InDirectory(newAssemblyFilter(AppDomain.CurrentDomain.RelativeSearchPath)) finds all my project dll's (there are 7 dll's). 3 of them contains implementation of IWindsorInstaller interface, for example:

class WindsorInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        var services = AllTypes.FromThisAssembly().Where(type => type.Name.EndsWith("Service"));
        container.Register(services
            .WithService.DefaultInterfaces()
            .Configure(c => c.LifestyleTransient()));
        container.Register(Component.For<ISession>().ImplementedBy<AspnetSession>().
            LifeStyle.Transient);
        container.Register(Component.For<ICache>().ImplementedBy<AspnetCache>().
            LifeStyle.Transient);
    }
}

But when I sets breakpoints, it is only 1 installer called, 2 other was skipped. It's funny, but I have another working project from what i copied code.

Your installer class should be public. Your current installer class has no access modifier, hence defaults to internal - and is invisible to Windsor. The Castle docs specify this here: https://github.com/castleproject/Windsor/blob/master/docs/installers.md .
