Failed to generate a user interface of SQL SERVER due to a failure in starting the process for the user interface

I got the above error when I want to check some Win Form samples with the SQL Server Express.

I found the following resources on the web, but non of them was able to resolve my problem. But one comment made by Manoj was to able to make it work even its not the solution.

I was satisfied with it since I wanted do some thing else with Windows forms. But need to find a solution in future.

So any of you have found a real solution to above please forward me....
