ADO.NET POCO Entity Generator is not launching in Visual Stusio 2010

When I add new item and choose the "ADO.NET POCO Entity Generator", I get an error message "this template attempted to load component assembly 'Microsoft.Data.Entity.Design, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. For more information on this problem and how to enable this template, please see documentation on Customizing Project Templates"

I get the same error when I choose the "ADO.NET DbConext Generator". There's a 4.2 version of it and it works.

I am using Visual Studio 2010 SP1 in windows 7 64bit. (Just reinstalled SP1), Entity Framework June 2011 CTP, and the just released Entity Framework 4.2. All the projects in the solution are taregting the CTP framework. I already ran devenv.exe /setup & devenv.exe /installvstemplates

I have two questions: How do I find out why ADO.NET POCO Entity Generator is not working? Is there a v4.2 version of it?

The error message seems to indicate the template tried to load Microsoft.Data.Entity.Design but there was a problem. I want to find what the problem was.

The version of Microsoft.Data.Entity.Design I have on my computer is 10.6.10617.1 while the template is looking for 10.0.0.0. What I did is rebuilt the vsix template extension to use 10.6 instead. There are a few templates in the gallery which produce this problem and these need to modified.

If you have CTP 2011 installed and if your project targets special CTP .NET 4.2 target you must use only features from CTP = only the POCO template shipped with CTP. Nothing else will work because CTP is intrusive and it breaks functionality of old EF features and designer.
