New Post: WPF: No current actions property

I have made my own UI like it is in WPFSetup sample.
But one small difference:
I do not use setup Datacontext for the page but this function

Setup.PropertyChanged += (s, e) =>

        {
            if (e.PropertyName == @"CurrentActionName")
            {
                this.OnPropertyChanged(@"CurrentActionName");
            }
            return;
        };

Some problems occur:

1. I do not see the current action names (even when I set setup.ProgressStepDelay = 50;)
2. Install, uninstall actions completed successfully but I receive a message
   "Failed. See log files for details" and log file like this
