Minimum IIS Requirements
Before installing the API, make sure that Internet Information Services (IIS), an optional component of Windows OS, is installed and properly configured. The API module requires IIS 7.5 or later (IIS 7.5 is included in Windows Server 2008 R2 and Windows 7).
The state of the IIS is checked automatically, along with other prerequisites, when you click Install Alloy Navigator Express API on the Advanced Installation page of the Alloy Navigator Express 8 Installer. The information is shown in the "Internet Information Services state" row of the Check Prerequisites window.
If the test fails, the Alloy Navigator Express 8 Installer displays a list of missing requirements. Review the requirements and install all listed IIS components manually.
NOTE: For details on IIS requirements and instructions on how to install them, see Internet Information Services (IIS) Requirements.
