States pane not visible in Blend 3

When I started to follow some of the video tuturial for Expression Blend 3, I noticed that States pane is not available when I work on the WPF project; however, it is there when I create a Silverlight project. Apparetly the state manager is part of WPFToolkit and the work arround this issue is explained in  team blog of the Expression Blend:

Here are the steps you need to follow to get to the VSM-for-WPF goodness:

1. Install the WPF Toolkit from http://www.codeplex.com/wpf/Release/ProjectReleases.aspx?ReleaseId=15598
2. Create the following registry value and make it non-zero. The value should be of type DWORD. Or run the appropriate .REG file attached to this post (or by clicking here).
3. 32 bit OS : HKLM/Software/Microsoft/Expression/Blend/EnableVSM
4. 64 bit OS : HKLM/Software/Wow6432Node/Microsoft/Expression/Blend/EnableVSM
5. If Blend was running during the previous step then restart it.
6. Create a new WPF project.
7. Add %Program Files%\WPF\WPF Toolkit\…\WPFToolkit.dll to the References folder (Right-click the References node in Project, then click Add Reference…).
8. Close and reopen Window1.xaml. The States pane will now appear for the project.
