System requirements

When planning your installation, Citrix recommends that you allow at least an additional 2 GB of RAM for StoreFront over and above the requirements of any other products installed on the server. The subscription store service requires a minimum of 5 MB disk space, plus approximately 8 MB for every 1000 application subscriptions. All other hardware specifications must meet the minimum requirements for the installed operating system.

Citrix has tested and provides support for StoreFront installations on the following platforms:

Upgrading the operating system version on a server running StoreFront is not supported. Citrix recommends that you install StoreFront on a new installation of the operating system. All the servers in a multiple server deployment must run the same operating system version with the same locale settings.

StoreFront server groups containing mixtures of operating system versions and locales are not supported. StoreFront server groups can contain a maximum of six servers. However, from a capacity perspective based on simulations, there is no advantage of server groups containing more than three servers. Ideally, all servers in a server group should reside in the same location (data center, availability zone), but server groups can span locations within the same region provided that links between servers in the group meet minimum latency criteria. See Scalability.

Microsoft Internet Information Services (IIS) and Microsoft .NET Framework are required on the server. If either of these prerequisites is installed but not enabled, the StoreFront installer enables them before installing the product. Windows PowerShell and Microsoft Management Console, which are both default components of Windows Server, must be installed on the web server before you can install StoreFront. The relative path to StoreFront in IIS must be the same on all the servers in a group.

The StoreFront installer will add the IIS features it requires. If you pre-install these features, below is the required list:

On all platforms:

On Windows Server 2008 R2:

On Windows Server 2012 R2:

On Windows Server 2016

StoreFront uses the following ports for communications. Ensure your firewalls and other network devices permit access to these ports.

StoreFront supports both pure IPv6 networks and dual-stack IPv4/IPv6 environments.

Infrastructure requirements

Citrix has tested and provides support for StoreFront when used with the following Citrix product versions.

Citrix server requirements

StoreFront stores aggregate desktops and applications from the following products.

NetScaler Gateway requirements

The following versions of NetScaler Gateway can be used to provide access to StoreFront for users on public networks.

Citrix Receiver for HTML5 requirements

If you plan to enable users to access desktops and applications using Citrix Receiver for HTML5 running on Receiver for Web sites, the following additional requirements apply.

For internal network connections, Citrix Receiver for HTML5 enables access to desktops and applications provided by the following products.

For remote users outside the corporate network, Citrix Receiver for HTML5 enables access to desktops and applications through the following versions of NetScaler Gateway.

For users connecting through NetScaler Gateway, Citrix Receiver for HTML5 enables access to desktops and applications provided by the following products.

User device requirements

StoreFront provides a number of different options for users to access their desktops and applications. Citrix Receiver users can either access stores through Citrix Receiver or use a web browser to log on to a Citrix Receiver for Web site for the store. For users who cannot install Citrix Receiver, but have an HTML5-compatible web browser, you can provide access to desktops and applications directly within the web browser by enabling Citrix Receiver for HTML5 on your Citrix Receiver for Web site.

Users with non-domain-joined desktop appliances access their desktops through their web browsers, which are configured to access Desktop Appliance sites. In the case of domain-joined desktop appliances and repurposed PCs running the Citrix Desktop Lock, along with older Citrix clients that cannot be upgraded, users must connect through the XenApp Services URL for the store.

If you plan to deliver offline applications to users, the Offline Plug-in is required in addition to Citrix Receiver for Windows. If you want to deliver Microsoft Application Virtualization (App-V) sequences to users, a supported version of the Microsoft Application Virtualization Desktop Client is also required. For more information, see Managing Streamed Applications. Users cannot access offline applications or App-V sequences through Citrix Receiver for Web sites.

It is assumed that all user devices meet the minimum hardware requirements for the installed operating system.

Requirements for Citrix Receiver-enabled stores

The following Citrix Receiver versions can be used to access StoreFront stores from both internal network connections and through NetScaler Gateway. Connections through NetScaler Gateway can be made using both the NetScaler Gateway Plug-in and/or clientless access. Citrix Receiver for Windows 4.3 is the minimum version required to receive the full StoreFront unified Citrix Receiver experience. See Support for the unified Citrix Receiver experience.

Requirements for access to stores through Citrix Receiver for Web sites

To access Citrix Receiver for Web sites from both internal network connections and through Citrix Gateway, use latest version of the following browsers:

On Windows

* Microsoft Edge (based on Chromium) is supported on Windows 10 only.

Note:

Citrix support is dependent on the official Microsoft support/extended support for the underlying OS and browser versions running on those OSs.

On Mac

On Linux

Connections through Citrix Gateway can be made using the Citrix Gateway plug-in, ICA proxy or clientless VPN (cVPN). Additionally, specific versions of Citrix Gateway are required to enable connections from outside the corporate network. For more information, see Infrastructure requirements.

Requirements for access to desktops and applications through Receiver for HTML5

The following operating systems and web browsers are recommended for users to access desktops and applications using Receiver for HTML5 running on Receiver for Web sites. Both internal network connections and connections through NetScaler Gateway are supported. However, for connections from the internal network, Receiver for HTML5 only enables access to resources provided by specific products. Additionally, specific versions of NetScaler Gateway are required to enable connections from outside the corporate network. For more information, see Infrastructure requirements.
