For Kentico to work correctly with your IIS, your [system](https://docs.kentico.com/k9/installation/server-and-hosting-requirements.md) needs to have the following features enabled:

- On Windows 7 and Server 2008 R2 SP1: **ASP.NET 4.5**, **.NET Extensibility**, **ISAPI Extensions**, **ISAPI Filters** and **Static Content**
- On Windows 8/8.1 and Server 2012/2012 R2: **ASP.NET 4.5**, **.NET Extensibility 4.5**, **ISAPI Extensions**, **ISAPI Filters** and **Static Content**
- On Windows 10: **ASP.NET 4.6**, **.NET Extensibility 4.6**, **ISAPI Extensions**, **ISAPI Filters** and **Static Content**

Check that the features are enabled in your system.

> **Note:** If these features are not enabled, the Kentico Installer might not detect that IIS is installed on your computer, and could additionally install IIS Express.
