I am messing around with embedding Flash (.swf) files inside my c# applications and I am really looking for a way to find out if the ActiveX control is already installed.   I would like to build a bootstrap application that can detect the existence of the .NET Framework (easy enough) and the existence of an installed Flash ActiveX control.

I know there are a million different ways of detecting it using javascript and what not, but I am really looking for a file or registry based detection model, if possible.

If anyone can suggest something, please post a comment.  Thanks!
