  • Try starting any application to force the download/run request; and/or
  • If this fails, you may need to check the security settings of your browser, additional browser toolbar (such as Google ToolBar) and/or anti-virus software for any enabled download-blocking options (and disable them accordingly).

Missing Citrix Online Plug-in

Problem:

  • A warning about a missing Citrix Online Plug-in shows up; and/or
  • Applications do not start.

 

Soluction:

The Citrix Web Interface needs a browser plug-in called Citrix Online Plug-in for Web to work properly.

This is usually "pushed" to your computer (be it Mac or Windows) by the Citrix Web Interface automatically on first login:

  1. Once logged in, the system will detect if the plug-in is missing and ask you to download it. Agree to the Terms & Conditions by ticking the relevant checkbox) then click on the Download button:

  2. Simply follow on-screen instructions to complete download and installation (which may vary depending on Operating System and browser used).
  3. Once completed, you may need to fully restart your browser and/or operating system in order for changes to take effect.

 

Citrix Online Plug-in Failing to Download or Install

Problem:

The Citrix Web Interface needs a browser plug-in called Citrix Online Plug-in for Web to work properly.

This is usually "pushed" to your computer (be it Mac or Windows) by the Citrix Web Interface automatically on first login and, depending on the security settings of your browser, this may be installed automatically thereafter or just downloaded (or requested to).

 

Solution:

If any of the two (installation or download) fail, try the following:

  • Check the security settings of your browser, additional toolbars within (e.g. Google Toolbar) or AntiVirus software for pop-up web-pages to be allowed.
  • Check the security settings of your borwser and/or additional toolbars (e.g. Google Toolbar) to allow download and installation of plug-ins.
  • When using Internet Explorer, install the additional Citrix Helper (ActiveX)Control (see further below).
  • Download and install the plug-in manually directly from the homepage of Citrix developer:

    http://www.citrix.com/

    As the plug-in gets updated often, the ICT prefers not to provide a direct download link. Instead, you are advised to use the site's search engine to look for the latest version by using the following search string: "citrix online plug in web".

    Once you find the most up-to-date plugin, be sure to download the Online version (NOT the Offline one!) according to your operating system (Mac or Windows). 

 

Citrix Helper Control from 'CITRIX SYSTEMS, INC' Missing

Problem:

When using Internet Explorer, depending on its security settings, a message about Citrix Helper Control from 'CITRIX SYSTEM, INC' message may appear.

The message may vary depending as well on your Internet Explorer version:
