Supported server-side configuration

We recommend you to install the following components on the computer where you want Kentico to run. However, if you do not install these components on your computer before installing Kentico, the new Kentico Installer is capable of downloading and installing them or their suitable alternatives (except for the operating system and the built-in Visual Studio server) on its own. Although, in such case, your computer must be connected to the Internet.

  • Windows Vista Home Premium/Business/Enterprise/Ultimate, Windows 7 (both 32bit and 64bit) or Windows 8 (both 32bit and 64bit), or their corresponding server versions – Windows Server 2008, 2008 R2, 2012.
  • Microsoft .NET Framework 4.0 or higher.
  • Microsoft Internet Information Services (see the table below) or Visual Studio/Visual Web Developer 2008/2010/2012 built-in web server. Depends on which server you choose to install your web project into.
  • Microsoft SQL Server 2005, 2008, 2008 R2, 2012 (including free SQL Server Express Edition 2005/2008/2012).
