Silverlight install error 1603 - 'Windows Installer Clean Up' to the rescue

Came across this error today whilst trying to install Silverlight for an enterprise LOB app, and as you know if you come across this error the support documentation on MSDN is pretty useless. The machine had the default Silverlight v3 install and we were trying to install an instance of v4.

So first thoughts was local admin rights - I didn't have them, after finding someone who did, it was still failing. Next attempt was following the steps defined here but even after uninstall\reinstall still no luck. I started to think this was going to be a long afternoon.

Then I remember a great little tool which is no longer available for download from MSDN -'Windows Installer Clean Up', great little tool for cleaning the registry and file system of installed applications, but in the wrong hands this can totally wreak a machine, the reason why MS pulled it from MSDN, article here. Fortunately for me there's a copy on the corporate network, it's got a rather strange filename - 'msicuu2.exe', if you don't have it to hand I'm sure you can find it somewhere on the internet :)

Make sure when you attempt to run this you're running as 'local admin'. Select the entry or entries for 'Microsoft Silverlight' - there could be more than one, in my case there was only a single entry for v3 and click 'Remove'.

Then hopefully Silverlight will install successfully - if it doesn't and it wreaks the machine it ain't my fault ;)

Implementing a busy indicator using a visual overlay in MVVM

This is a technique we use at work to lock the UI whilst some long running process is happening - preventing the user clicking on stuff whilst it's retrieving or rendering data. Now we could have done this by launching a child dialog window but that feels rather out of date and clumsy, we wanted a more modern pattern similar to the way <div> overlays are done on the web. Imagine we have the following simple WPF app and when 'Click' is pressed a busy waiting overlay is shown for the duration entered into the text box. What I'm interested in here is not the actual UI element of the busy indicator but how I go about getting this to show & hide from when using MVVM. The actual UI elements are the standard Busy Indicator coming from the WPF Toolkit : The XAML behind this window is very simple, the important part is the ViewHost. As you can see the ViewHost uses a ContentPresenter element which is bound to the view model, IMainViewModel, it contains 3 child v...

Showing a message box from a ViewModel in MVVM

I was doing a code review with a client last week for a WPF app using MVVM and they asked ' How can I show a message from the ViewModel? '. What follows is how I would (and have) solved the problem in the past. When I hear the words ' show a message... ' I instantly think you mean show a transient modal message box that requires the user input before continuing ' with something else ' - once the user has interacted with the message box it will disappear. The following solution only applies to this scenario. The first solution is the easiest but is very wrong from a separation perspective. It violates the ideas behind the Model-View-Controller pattern because it places View concerns inside the ViewModel - the ViewModel now knows about the type of the View and specifically it knows how to show a message box window: The second approach addresses this concern by introducing the idea of messaging\events between the ViewModel and the View. In the example ...

WPF tips & tricks: Dispatcher thread performance

Not blogged for an age, and I received an email last week which provoked me back to life. It was a job spec for a WPF contract where they want help sorting out the performance of their app especially around grids and tabular data. I thought I'd shared some tips & tricks I've picked up along the way, these aren't probably going to solve any issues you might be having directly, but they might point you in the right direction when trying to find and resolve performance issues with a WPF app. First off, performance is something you shouldn't try and improve without evidence, and this means having evidence proving you've improved the performance - before & after metrics for example. Without this you're basically pissing into the wind, which can be fun from a developer point of view but bad for a project :) So, what do I mean by ' Dispatcher thread performance '? The 'dispatcher thread' or the 'UI thread' is probably the most ...
