Hello
i opened the choose items dialog , and looked at the path of the Dlls that are displayed there .
I found that the reference leads to the Demo , which i al ready removed using the Add remove programs before i installed the Retail .
Anyways , i started empty project , then added reference first to the Dlls which is in the retail directory .
After that right clicked toolbox and i unchecked the llbl items from the choose items dialog and closed the dialog .
After that i dragged the retail dll to the toolbox and the retail controls were added .
Now dragging them to the design surface worked without problem .
