ArcGIS Web Adaptor system requirements


Windows Server 2012 R2 and Windows 8.1 are supported at 10.2.1 and later versions. These operating systems are not supported at 10.2.

The system specifications, including hardware requirements, supported operating systems, and web servers, required to run the ArcGIS Web Adaptor are listed below.

Supported operating systems

The operating systems below satisfy the minimum operating system requirements:


Windows 8.1, 8, 7, and Vista are supported for basic testing and application development use only. They are not recommended for deployment in a production environment.

Disk space requirements

The Web Adaptor requires 16 MB of disk space.

Microsoft .NET Framework 3.5 SP1, 4.0, and 4.5 support

The Web Adaptor requires Microsoft .NET Framework 3.5 Service Pack 1 (SP1), 4.0, or 4.5 in order to be installed. Each supported version of Microsoft .NET Framework is available for download on the installation media. However, on Windows 7 and Windows Server 2008 R2, Microsoft .NET Framework 3.5 SP1 must be installed using Windows Features. Follow the instructions below to install version 3.5 SP1 on Windows 7 and Windows Server 2008 R2:

Windows Server 2008 R2

Open Server Manager > Features > Add Features. Enable and install Microsoft .NET Framework 3.5.1.

Windows 7

Go to Control Panel > Programs and Features > Turn Windows Features on or off. Enable and install Microsoft .NET Framework 3.5.1.

Microsoft Internet Information Services (IIS) 7.0 or higher

The Web Adaptor supports IIS versions 7.0, 7.5, 8.0, and 8.5. IIS must be enabled along with specific IIS 7.0, 7.5, 8.0, and 8.5 components. The setup will not proceed if IIS is not detected and specific IIS components enabled.

If you already have IIS installed but are missing required IIS components, the setup will display the IIS requirements verification dialog box. This gives you the option to allow the installation to automatically enable any missing required IIS components. To do this, click I agree. To learn more, see Automatically enabling IIS components.


If you are going to perform a silent installation of the Web Adaptor, all required IIS components must be enabled manually. The Web Adaptor setup will not automatically enable missing IIS components when you are performing a silent installation.

To learn how to enable IIS on your operating system and optionally enable the missing IIS components on your own, see the topics below.
