When users launch a Citrix-published desktop or application from the Workspace ONE Intelligent Hub portal or app, an ICA file is downloaded and passed to the Citrix Workspace app or Citrix Receiver. Citrix Workspace app and Citrix Receiver are native OS applications which launch Citrix-published desktops and applications. The launch experience varies across different platforms and browsers.

Launch Process

Depending on the platform and browser, the application or desktop is launched differently. In some cases the application or desktop is launched directly. In other cases, the user needs to associate the .ica file type with the Citrix Workspace app or Citrix Receiver first so that the application or desktop can be launched directly. In a few cases, the user needs to click the downloaded ICA file to launch the application or desktop. See the table for detailed information.

Platform Browser How the application or desktop is launched Action Required

Chrome Launches the application or desktop directly. None
Internet Explorer Downloads the ICA file with a .ica extension. After the file type is associated with the Citrix Workspace app or Citrix Receiver, launches the application or desktop automatically. In the browser, associate the .ica file type with the Citrix Workspace app or Citrix Receiver.

Note: There is a known issue with application launch on Chrome browsers related to NPAPI plugins. If users are unable to launch their applications or desktops on Chrome, you can turn off the Workspace ONE Access feature flag orgUseNonNPAPIForCitrixLaunch. With the feature flag turned off, the browser downloads the ICA file and users can click it to launch their application or desktop.
