Invoke or BeginInvoke cannot be called on a control until the window handle has been created..

November 21, 2010

If you installing new instance of SQL Server 2008 or adding new features to an existing one and got this error

SQL Server Setup has encountered the following error:
Invoke or BeginInvoke cannot be called on a control until the window handle has been created..

I won’t recommend you to go to http://support.microsoft.com/kb/975055 and waste your time installing SQL Server 2008 SP 1 because it won’t solve the problem.

Solution
Close IE\Explorer windows or anything you can open after doing your installation process 🙂 yes that’s it… weird..
