Summary

This article describes how to remove the Citrix ICA Client or Online plug-in for Windows using the Windows Installer Uninstall String (for MSI files) or InstallShield (for EXE files).

Background

IMPORTANT NOTE: Starting with the release of Online plug-in version 11.2 and going forward, the installer is a EXE wrapper that is used to install the various components of the Online plug-in (a.k.a. Receiver). The instructions in this article do not apply these versions of the client. Command line instructions for uninstalling these versions of the client can be found in Citrix eDocs, under the section for your version of the Online plug-in/Receiver.

While an upgrade option is available during the installation of the ICA Client for Windows, it is strongly recommended that you remove earlier versions of the ICA client before installing the latest client. This will help to avoid potential configuration conflicts.

The following procedure is intended for environments where the ICA Client was not deployed using Active Directory (AD), Systems Management Server (SMS), or other third-party application that could otherwise be used to automate removal of the client. It is presumed that the following procedure will be implemented using a script that can be invoked through a logon script prior to deploying the latest client (e.g. via a batch file or Visual Basic Script).

Procedure

The process for uninstalling the currently installed Citrix ICA client depends on the installation file type used to install the client.

InstallShield must be used to remove the client if an EXE file was used for installation – this was typical for Citrix ICA Client versions 6.x through 8.x.

• The InstallShield command to remove a client installed using an EXE file is: isuninst –f C:\PROGRA~1\Citrix\ICACLI~1\Uninst.isu –c C:\PROGRA~1\Citrix\ICACLI~1\uninstpn.dll –a

• The -a switch at the end of the ISUNINST command line indicates a silent removal

• The command to remove the web client InstallShield package is: %SystemRoot%\system32\ctxsetup.exe /uninst C:\PROGRA~1\Citrix\icaweb32\uninst.inf

In later versions the client starting in version 9.x were installed using a Microsoft Installer (MSI) package, and therefore the MSI file may be used to remove the client.

• The Windows Installer command to remove a client installed with an MSI file is: msiexec.exe /x GUID REBOOT=ReallySuppress /qb!

• msiexec.exe /x {7A1FB67F-A340-472A-97C3-A6AFFE078AAE} REBOOT=ReallySuppress /qb!

• Refer to the Microsoft KB for further information on Windows Installer command-line options.

A list of Globally Unique Identifiers (GUIDs) for public releases of the Citrix ICA Client for Windows can be found at the end of this article. It is recommended you confirm the exact GUID for the installed version, particularly if you are using a private release of the client provided by Citrix Technical Support. The GUID can be found in the following registry key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall.

Once you have selected the Uninstall key, press Ctrl-F and search for the term “Citrix”. The sub-key containing the Citrix ICA client entry appears as opened (left pane) and is labeled with the GUID.

Note: For x64 systems, check the same path but under the Wow6432Node key.

The table below provides the version, build, GUID, and release dates for public releases of the Citrix ICA Client.

Note: Adding the Client Version column to the Access Management Console while viewing session information is useful in determining the versions of the Citrix ICA Client currently in use in your environment.
