I thought it was time to start trying out some Windows Presentation Foundation (WPF). So I downloaded the latest VPC with Orcas CTP (June 2007) and Expression Blend 2 (May Preview). But starting the Expression Blend 2 setup gives an error about the .NET 3.0 framework that needs to be installed. After some research I found out .NET 3.0 SP1 is installed on the Orcas VPC. Some more research gives the following solution.

You can fool the Expression Blend 2 setup by changing a registry key. Follow the steps:

• Search for the "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup\Windows Presentation Foundation\ProductVersion" registry key
• My original ProductVersion value is: 3.0.04506.577
• I changed it to ProductVersion: 3.0.6913.0
• I ran the Expression Blend 2 setup
• And changed the ProductVersion back to: 3.0.04506.577

Now let's play with WPF.
