Captiva "An error has occurred configuring the InputAccel Web Component application pool. Check the user running installer has administrator privileges"

Error Description:

Installation: "An error has occurred configuring the InputAccel Web Component application pool. Check the user running installer has administrator privileges"

The solution from below worked for me:

 If installing InputAccel on a machine running Windows Server 2008 R2 or Windows 7: in addition to the settings that enabled for a standard IIS 7.5 configuration, enable these additional role services settings:

• Application Development
  • ASP.NET
  • .NET Extensibility
  • ISAPI Extensions
  • ISAPI Filters

• Security
  • Basic Authentication
  • Windows Authentication
  • IIS Client Certificate Mapping Authentication

• IIS 6 Management Compatibility
  • IIS 6 Metabase Compatibility
  • IIS 6 WMI Compatibility
  • IIS 6 Scripting Tools
  • IIS 6 Management Console
