Invoke or BeginInvoke cannot be called on a control until the window handle has been created
Ao tentar instalar o SQL Server 2008 Express em uma máquina com Windows 7, me retornou o seguinte erro :
“Invoke or BeginInvoke cannot be called on a control until the window handle has been created.”
Para contornar, basta executar a instalação novamente
