Questions or Problems

Citrix-Receiver for HTML5

The Citrix receiver for HTML5 used in Citrix Portal Neptun is operating system independent and a client installation is not necessary - see Access - Quickstart - above

After successful login and start of the selected application another browser tab opens. The tab corresponds to a connection to the server (session) in which the application was started and is displayed. If several applications are started that are also installed on the server, they are displayed in the same tab. Applications that are displayed in another tab are installed on other servers - new sessions to the server, for example Knime or DATEV.

Each tab contains the menu of the Citrix receiver, which is located at the top in the middle of the tab and is displayed completely by a single click (see illustrations).

startup behavior

The startup behavior depends on the installation location of the applications, i.e. applications installed on a server start faster after the initial logon. An initial logon corresponds to logging on to a terminal server or desktop PC and is performed automatically when the first application is started. Most standard applications are installed on a server, for example, the applications in the Web Research and Office 2016 categories, which means that applications from this area start immediately from the second application.

Special applications such as DATEV, Oracle or Knime are installed on independent servers, which means that a further initial logon (approx. 20s) is performed when such an application is started.

menu bar

The following icons are included in the menu bar, the meaning of which can be seen in the table below.
