SQL Server 2008 SP1 Invoke or BeginInvoke cannot be called on a control unit until the window handle has been created

Later today, I was preparing some new virtual images for a new SharePoint 2010 installation. I wanted to upgrade my MS SQL Server 2008 to SP1 but came across this message:

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

To solve the issue make sure the following server features are installed:
.NET Framework 3.5.1 Features -> .NET Framework 3.5.1
Windows Process Activation Service -> .NET Environment

After that restart the installation and everything should be fine !
