Horizon desktops, Citrix published apps, and ThinApp resources require the following helper applications be installed on the users’ computers or device.

  • Horizon desktops use Horizon Client.
  • Citrix-published apps require Citrix Receiver.

Users are asked to download helper applications to their desktop or device the first time they launch applications from these resources types. You can completely disable this prompt from displaying each time the resource is launched from the Catalog > Settings > Global Settings page.

Disabling the prompt from display is a good option when computers or devices are managed, and you know the helper applications are on the user's local image.


  1. In the Catalog tab, select Settings > Global Settings.
  2. Select the operating systems that should not ask to launch the helper applications.
  3. Click Save.
