After installation when I open the default web page to access the software I receive and error saying HTTP Error 404.2 – Not Found. The page you are requesting cannot be served because of the ISAPI and CGI Registration list settings on the Web server (Fig 1).

  • ISAPI and CGI scripts are currently restricted on your web server for the .net framework. To enable these, go to Windows Start Menu – Control Panel – Administrative Tools – Internet Information Services (IIS) Manager. This will load the IIS Manager. Locate the section marked ISAPI and CGI Restrictions (Fig 2) and double click it.

Local any entry that relates to ASP.NET version 4 and ensure that the Restriction is set to Allowed. If any are set to Not Allowed, right click and select Allow. Once you have changed the setting for all instances of version 4 try accessing the web page again.
