When the smarthelpsetup.html page displays an error, additional information is available by appending ?diagnosticmode to the URL. For example:
http://<server>/<content_directory>/smarthelpsetup.html?diagnosticmode
In most cases, after you restart the browser the new toolbar button will appear automatically. However, if the user has customized the Internet Explorer toolbar, the new button may not appear. In this case, the toolbar button is added to the choices in the Customize Toolbar dialog box, and it will appear if the toolbar is reset. For more information, see the article on the Microsoft Developer Network at http://msdn2.microsoft.com/en-us/library/Aa753588.aspx.
Depending on the version of Internet Explorer you are using, the entire toolbar may not display. The SmartHelp button will be added in the dropdown list area for more buttons.
