ArcGIS Server 11.3 system requirements

The system and hardware requirements to run ArcGIS Server are listed below.

It's recommended that you review the deprecation notice to determine whether your hardware and software components are still compatible with the current ArcGIS version.

ArcGIS Notebook Server has additional requirements. See ArcGIS Notebook Server system requirements.


ArcGIS Enterprise components require the Microsoft Visual C++ 2015–2022 Redistributable (x86 and x64) minimum version 14.38.33130. Obtain the Microsoft Visual C++ Redistributable for Visual Studio 2015–2022 file from the Microsoft site.

If the required Visual C++ Redistributable is not already installed, running the ArcGIS Server setup.exe file will install it. Running the ArcGIS Server setup.msi file will not install it. Therefore, to run the ArcGIS Server setup.msi file, the Microsoft Visual C++ 2015 - 2022 Redistributable must already be installed.

Microsoft Windows operating system requirements

The following 64-bit operating systems satisfy the minimum operating system requirements. Support is not provided for 32-bit operating systems; the setup only proceeds if the operating system is 64 bit.

Windows 10 Pro and Enterprise

April 2024 update


  • Prior and future updates or service packs for these operating system versions are supported unless otherwise stated. The operating system version and updates must also be supported by the operating system provider.
  • ArcGIS is only supported on 64 bit CPUs with x86-64 architecture.
  • The Desktop Experience option is required on all versions of Windows Server.
  • Windows 11 and 10 are supported for basic testing and application development use only.
  • Machines with an underscore (_) in their names are not supported. Several widely used internet host name specifications have designated the underscore character as nonstandard. Although Microsoft Windows allows you to use the underscore in a machine name, it can still cause problems when you interact with other servers and platforms. For this reason, the installation will not proceed on servers that have an underscore in the host name.
  • You cannot install on domain controllers. Installing on a domain controller may adversely affect functionality.

Hardware requirements

The minimum RAM requirement for ArcGIS GIS Server, ArcGIS GeoEvent Server, ArcGIS Image Server, or ArcGIS Knowledge Server is 8 GB per machine.

For a production environment, hardware requirements are not listed because the user and business needs of the software may vary. These requirements must be considered in determining hardware needs to meet performance and scalability expectations.

ArcGIS GeoAnalytics Server requires a minimum of 16 GB of RAM per machine.

When configuring ArcGIS GeoAnalytics Server, ensure that the drive hosting the user profile has sufficient temporary space available or modify the GeoAnalytics Server temporary file location after installation. When determining a sufficient value, consider the input data size, the type of GeoAnalytics task, and the number of nodes in your site.

See Best practices for GeoAnalytics Server sites for more information on deploying ArcGIS GeoAnalytics Server.

ArcGIS Server requires a minimum of 10 GB of available disk space.

Firewall settings

ArcGIS Server communicates on specific ports. You must open these ports on your firewall before installing the software. For more information on the ports ArcGIS Server requires for communication, see Ports used by ArcGIS Server.

Domain name system (DNS) and fully qualified domain name (FQDN) recommendations

If you'll be federating your site with an ArcGIS Enterprise portal, it's recommended that you configure your organization's domain name system (DNS) to include fully qualified domain name (FQDN) entries for each site you intend to federate with the portal. Portal for ArcGIS will request the FQDN of each site when you federate.

SSL certificates

ArcGIS Server comes configured with a self-signed certificate, which allows you to do initial testing of the ArcGIS Server site and helps you quickly verify that your installation was successful. You must request a certificate from a trusted certificate authority (CA) and configure the ArcGIS Server site to use it. This could be a domain certificate issued by your organization or a CA-signed certificate.

Like ArcGIS Server, Portal for ArcGIS also comes with a configured self-signed certificate. If you'll be federating an ArcGIS Server site with an ArcGIS Enterprise portal, you should request a certificate from a trusted CA and configure the portal to use it. For more information, see Security best practices.

.NET 8 requirement for .NET Extension Support

The .NET Extension Support feature, supporting .NET-based Server Object Extensions (SOEs) and Server Object Interceptors (SOIs), requires .NET 8. If .NET 8 is not found, the .NET Extension Support feature will not be available for installation.

If you use .NET-based SOEs or SOIs, you must install either .NET Desktop Runtime 8 (x64) or .NET SDK 8 (x64) prior to installing ArcGIS Server.

Geoprocessing requirements

If you use the ArcGIS Pro-based geoprocessing tools that are installed with ArcGIS Server, see ArcGIS Server and ArcPy for where to find the Python 3 files.

Page file size requirements

Ensure that a sufficient page file size is configured for the ArcGIS Server machine. You should consult with your IT administrator or follow best practices from Microsoft.

When using ArcGIS GeoAnalytics Server, the Windows page file can use up to three times the available physical RAM when working on memory-intensive tasks. To avoid system failures and depleted disk space, move the page file to a volume with at least three times the physical RAM available space.

Supported web browsers

ArcGIS Server Manager requires one of the following web browsers:

  • Google Chrome version 118 and later
  • Microsoft Edge version 118 and later
  • Mozilla Firefox version 121 and later
  • Mozilla Firefox version 115 (ESR)
  • Safari version 16 and later

Supported virtualization environments and cloud platforms

Virtualization and cloud environment support is the same for all components of a base ArcGIS Enterprise deployment. See ArcGIS Enterprise on cloud platforms and Supported virtualization environments in the ArcGIS Enterprise system requirements for details.

Supported databases

See the requirements for each database that can be registered with ArcGIS Server sites:

Software version requirements

If the ArcGIS Server site acts as the hosting server for an ArcGIS Enterprise deployment, the ArcGIS Server software version must be the same as the other base ArcGIS Enterprise components.


ArcGIS Server 11.0 and later cannot be installed on the same machine as any version of ArcMap, ArcReader, and ArcGIS Engine clients.

Coordinate system files

Stand-alone and hosting server sites may require additional coordinate system files. See Coordinate system requirements for more information.
