Can't add Ado .Net Entity Data Model

问题

I'm doing these steps:

1. Create new vs2010 C# console application
2. Project menu -> Add New Item
3. select Ado.NET Entity Data Model -> click Add
4. Entity Data Model wizard window opened.
5. Select Generate From database -> Click Next
6. The next window appears for less than 1 second and it gets closed automatically.

I tried to reset vs2010 setting but no good news, the problem still exist.

I also tried it with ASP.NET Website.

What is the problem?

I had a similar problem and finally fixed it by deleting
