Redistributing Web Client Applications
If your application uses the MFC classes implementing the WebBrowser control (for example, CHtmlView or CHtmlEditView), Microsoft Internet Explorer 4.0 or later must at least be minimally installed on the target computer.
Installing the latest version of Internet Explorer also ensures that the target computer has the latest common control files.
Information about installing minimal Internet Explorer components is available in the following Knowledge Base article:
