System requirements and compatibility 编辑

Requirements

• Minimum 1 GB RAM.
• Microsoft Edge WebView2 Runtime version 99 or later.

  Note:

  Starting with Citrix Workspace app version 2107, Microsoft Edge WebView2 Evergreen Bootstrapper is packaged with the Citrix Workspace app installer. The Evergreen Bootstrapper is the tiny installer that downloads the WebView2 Runtime version matching the device architecture and installs it locally.

  During Workspace app installation, the installer checks whether the Microsoft Edge WebView2 Runtime is present on the system and installs it if not found.

  You must be connected to the internet to download and install Microsoft Edge WebView2 Runtime.

  When you try to install or upgrade Citrix Workspace app with non-administrator privileges and Microsoft Edge WebView2 Runtime isn’t present, the installation stops with the following message:

  ‘You must be logged on as an administrator to install the following prerequisite packages:

  Edge Webview2 Runtime’

• Self-Service plug-in requires .NET 4.8. It allows you to subscribe to and launch the apps and desktops from the Workspace app user interface or command line. For more information, see Using command-line parameters.

  When you try to install or upgrade to Citrix Workspace app 1904 or later and the requisite .NET Framework version isn’t available on your Windows system, the Citrix Workspace app installer downloads and installs the required .NET Framework version.

  Note:

  The installation fails when you try to install or upgrade Citrix Workspace app with non-administrator privileges and .NET Framework 4.8 or greater isn’t present on the system.

• Latest version of Microsoft Visual C++ Redistributable.

  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 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.

  For troubleshooting issues with the .NET Framework or the Microsoft Visual C++ Redistributable installation, see Citrix Knowledge Center article CTX250044.

Note:

You must be connected to the internet to download and install .NET Framework and Microsoft Visual C++ Redistributable. If not, the administrator can install these requirements using a deployment method, for example, SCCM.

Windows 10 or 11 Compatibility with Citrix Workspace app for Windows

With the Windows 10 Operating System, Microsoft introduced a new way to build, deploy, and service Windows: Windows as a service. New features are packaged into Feature Updates (major versions like 1703, 1709, 1803). Bug fixes and security fixes are packaged into Quality Updates. These updates that can be deployed using existing management tools like SCCM.

Note:

• We don’t recommend installing Citrix software versions that are earlier to the Semi-Annual Channel version.
• Once a Windows 10 version reaches End of Service that version is no longer serviced or supported by the Microsoft. Citrix supports running its software only on an operating system that its manufacturer supports. For information about Windows 10 End of Service, see Microsoft’s Windows Lifecycle Fact Sheet.

The following table lists the Windows 10 version number and the corresponding compatible Citrix Workspace app for Windows release/s.

Note:

Windows 10 versions are compatible with mentioned Citrix Workspace app versions only. For example, Windows 10 Version 21H1 isn’t compatible with the version earlier than 2106.

The following table lists the Windows 11 version number and the corresponding compatible Citrix Workspace app for Windows releases.

Validating free disk space

The following table provides details on the required disk space to install the Citrix Workspace app.

Citrix Workspace app does a check for the required disk space to complete the installation. The verification is done both during a fresh installation and an upgrade.

During a fresh installation, the installation stops and the following dialog appears when there’s insufficient disk space:

When you’re upgrading Citrix Workspace app, the installation ends and the following dialog box appears when there’s insufficient disk space.

Note:

• The installer does the check on the disk space only after extracting the installation package.
• When the system is low on disk space during silent installation, the dialog does not appear but the error message is recorded in the CTXInstall\_TrolleyExpress-\*.log.

Connections, Certificates, and Authentication

Connections

• HTTP store
• HTTPS store
• Citrix Gateway 10.5 and later

Certificates

Note:

Citrix Workspace app for Windows is digitally signed. The digital signature is time-stamped. So, the certificate is valid even after the certificate is expired.

• Private (self-signed)
• Root
• Wildcard
• Intermediate

Private (self-signed) certificates

If a private certificate exists on the remote gateway, install the root certificate of the organization’s certificate authority on the user device that’s accessing the Citrix resources.

Note:

If the remote gateway’s certificate cannot be verified upon connection, an untrusted certificate warning appears. This warning appears when the root certificate is missing in the local Keystore. When a user chooses to continue through the warning, the apps are displayed but cannot be launched.

Root certificates

For domain-joined computers, you can use a Group Policy Object administrative template to distribute and trust CA certificates.

For non-domain joined computers, the organization can create a custom install package to distribute and install the CA certificate. Contact your system administrator for assistance.

Wildcard certificates

Wildcard certificates are used on a server within the same domain.

Citrix Workspace app supports wildcard certificates. Use wildcard certificates by following your organization’s security policy. An alternative to wildcard certificates is a certificate with the list of server names and the Subject Alternative Name (SAN) extension. Private and public certificate authorities issue these certificates.

Intermediate certificates

If your certificate chain includes an intermediate certificate, the intermediate certificate must be appended to the Citrix Gateway server certificate. For information, see Configuring Intermediate Certificates.

Authentication

Authentication to StoreFront

* With or without the Citrix Gateway plug-in installed on the device.

Note:

Citrix Workspace app supports two-factor authentication (domain plus security token) using Citrix Gateway to the StoreFront native service.

Certificate revocation list

Certificate revocation list (CRL) allows Citrix Workspace app to check if the server’s certificate is revoked. The certificate check improves the server’s cryptographic authentication and the overall security of the TLS connection between the user device and a server.

You can enable CRL checking at several levels. For example, it’s possible to configure Citrix Workspace app to check only its local certificate list or to check the local and network certificate lists. You can also configure certificate checking to allow users to log on only if all the CRLs are verified.

If you’re configuring certificate checking on your local computer, exit Citrix Workspace app. Check if all the Citrix Workspace components, including the Connection Center, are closed.
