Under certain circumstances, uninstalling older versions of Receiver for Windows may leave some files behind on the computer and in the registry.This article can also be used as reference to completely clean a system after uninstalling a legacy ICA Client or Citrix Online Plug-in version.
Note: If you plan to install a currently supported version of Receiver for Windows on the system (version 4.4 or later) then there is no need to perform these manual steps or run the clean-up utility. As per article CTX136410, Receiver for Windows 4.4 and later no longer require the separate Clean-Up Utility before installing or upgrading over a previously installed version of Receiver for Windows.

2. In the %userprofile%AppData folder

   • Delete the ICAClient folder if it exists.

VA supports remote access with two different applications 1. Citrix Access Gateway (CAG) and 2. CISCO RESCUE VPN Client.

The CISCO RESCUE VPN Client is only for use on VA Government Furnished Equipment (GFE) and is installed on all GFE laptops. Users would still need to request remote access and have their remote access accounts enabled for use with either CAG or RESCUE.
