Installation methods

Compatibility with the higher versions of .NET

Citrix Workspace app for Windows version 2405 or later is compatible with the higher versions of .NET that are supported on your system. To ensure this compatibility, Citrix Workspace app follows these installation rules:

• If.NET isn’t installed on the system or a version less than 8.0.4 is installed on the system, Citrix Workspace app installs .NET version 8.0.4.
• If you install any supported higher version of .NET, Citrix Workspace app is compatible with the highest available .NET version. For example, you can install .NET 9.x and uninstall .NET 8.0.4. In this case, Citrix Workspace app uses the .NET 9.x version.

Microsoft Visual C++ Redistributable requirements

Citrix Workspace app requires the latest version of Microsoft Visual C++ Redistributable. The minimum version required for Citrix Workspace app for Windows 2405.10 or later is 14.40.33810.0.

Note:

Citrix recommends that you use the latest version of Microsoft Visual C++ Redistributable. Otherwise, a restart prompt might appear during an upgrade.

Starting with Version 1904, Microsoft Visual C++ Redistributable installer is packaged with the Citrix Workspace app installer. During Citrix Workspace app installation, the installer checks whether the Microsoft Visual C++ Redistributable package is present on the system and installs it if necessary.

Note:

If Microsoft Visual C++ Redistributable package doesn’t exist on your system, Citrix Workspace app installation with non-administrator privileges might fail.

Only an administrator can install the Microsoft Visual C++ Redistributable package.

Connectivity requirements

Feature flag management

Feature flags are used to enable or disable features dynamically. If an issue occurs with Citrix Workspace app in production, the affected feature can be disabled dynamically, even after the feature is shipped.

No configurations are needed to enable traffic for feature management, except when a firewall or proxy is blocking outbound traffic. In such cases, you need to enable traffic using specific URLs or IP addresses, depending on your policy requirements.

From Citrix Workspace app version 2409 onwards:

To ensure optimal functionality and access to preview features, you need to enable traffic to the URL features.netscalergateway.net.

Note:

Adding the preceding URL to the allow list is essential for optimal use of Citrix feature flags and is supported starting with version 2409 of the Citrix Workspace app for Windows.

Before Citrix Workspace app version 2409:

You need to enable traffic to the following URLs:

• events.launchdarkly.com
• stream.launchdarkly.com
• clientstream.launchdarkly.com
• Firehose.launchdarkly.com
• mobile.launchdarkly.com

List IP addresses in an allow list

If you must list IP addresses in an allow list, for a list of all current IP address ranges, see LaunchDarkly public IP list. You can use this list to know that your firewall configurations are updated automatically in keeping with the infrastructure updates. For details about the status of the infrastructure changes, see the LaunchDarkly Status page.

LaunchDarkly system requirements

Verify if the apps can communicate with the following services if you have split tunneling on the Citrix ADC set to OFF for the following services:

• LaunchDarkly service
