Receiver for Windows
This article explains how to remove client files remaining on system after uninstalling Receiver for Windows.


In some cases, uninstalling the Receiver for Windows (formerly ICA Client, Online plug-in, and so on) leaves some files behind on the computer and in the registry.

This article describes the files to be manually removed to avoid any unexpected behaviors if the Receiver is reinstalled anytime. This article can also be used as reference to completely clean a system after uninstalling a legacy ICA Client version, and prior to installing the latest Citrix Receiver for Windows.

After uninstalling Receiver and restarting the system, the following steps guide to remove any unnecessary files manually that might have been left on the client system.

It is important to remember that certain items mentioned in the following section might not exist on your system depending on the Receiver package used for the installation and how the package was deployed, for example per-machine against per-user installation.
More information on this is available in the Receiver and Plug-ins section of the?? Citrix eDocs?? for your version.

Following are the steps for cleaning up the file system:

  1. On the system in use, show all hidden system files and folders (Explorer’s Tools > Folder Options menu item).

  2. In the %userprofile%\AppData folder (%userprofile%\Application Data on Windows XP):

    • Delete the \ICAClient folder if it exists.

    • If the Program Neighborhood Agent was present on the system, the following folder might also exist and should be deleted:

    • For more recent Citrix Receiver releases, remove the following folders in \AppData if they exist:

      • \Citrix\Receiver
      • \Citrix\AuthManager
      • \Citrix\SelfService
    • On Windows 7, the files and folders mentioned in the preceding must be deleted in both of the following locations:

      • \AppData\Local
      • \AppData\Roaming
  3. Repeat everything mentioned in preceding Step 2 for the?? C:\Users\Default?? folder as well (C:\Documents and Settings\Default User?? on Windows XP).

  4. If they exist, ensure the following folders are removed from the directory in which the Receiver was installed. For example, the default install directory is?? %programfiles%\Citrix (%programfiles(x86)%\Citrix?? on 64-bit systems).

    • %programfiles%\Citrix\ICA Client
    • %programfiles%\Citrix\AuthManager
    • %programfiles%\Citrix\SelfServicePlugin
