Well, that was easy. You don't have any code that actually launches what you downloaded, so that's why it doesn't launch what you downloaded.
You might want to look at the Run method
] of the WScript.Shell object you created to do that.
Or, you can also use the Exec method
] of a Wscript.Shell object.
Or, you can use the ShellExecute method
] of a Shell.Application object. This is equivalent to clicking on Start/Run in Explorer.
