The engine runs asynchronously on a separate thread. Try removing the this.Close and see if it works.

In it I have 2 buttons. In the click event handlers I set some variables so I can only determine which features of the product I need to install. When I execute the InstallCommand it doesn't start the install, instead the log says canceling... My code is... this.InstallCommand = new DelegateCommand(() => this.model.PlanAction(LaunchAction.Install), () => this.State == InstallState.NotPresent); public InstallView(InstallViewModel viewModel) { InitializeComponent(); this.DataContext = viewModel; this.viewModel = viewModel; model = viewModel.model; this.Closed += (sender, e) => viewModel.CancelCommand.Execute(this); } private void btnInstallClientOnly_Click(object sender, RoutedEventArgs e) { model.SetInstallClient("InstallClient", 1); model.SetInstallServer("InstallServer", 0); if (viewModel.InstallCommand.CanExecute(null)) { model.LogMessage("Executing Install Command"); viewModel.InstallCommand.Execute(null); } this.Close(); } This is the log output...
