Embed Flash control in C# Windows Form

I am using 64 bit Windows 7, and Microsoft Visual C# 2008. I have a standalone project and I want to play a Flash movie in a control. The successful project should be able to create a Windows Form, embed a Flash movie control, and it should work in 64 bit Windows 7 and Visual C# 2008 or later. It should be able to run a Flash movie from the Internet. Basically, I am having trouble getting the Shockwave Flash object to work -- at runtime, I receive a message "class not registered".
