Citrix Online Plug-in v12.1.44.1 brings IE9 support

imageCitrix have released a minor upgrade for their now pretty aged v12.1 of the Citrix Online Plug-in, which has been the current version of the client since November 2010.  This is to fix issues which some users had in launching applications after they upgraded to Internet Explorer 9.

IE9 is a little annoying at the best of times with Citrix’s Web Interface as it now often asks you to download and open an ICA file instead of just launching your application, but some users have reported that they don’t even get the option to open the ICA file with the old version, v12.1.0.30, due to a sharing violation. The problem was certainly not seen by everyone – I have been using IE9 with more than one Web Interface site for over a month without issue.  Users on the same sites and same browser and OS versions reported issues to me.

The new client has no other fixes listed than support for IE9 (which can still display the ICA download popup message – but it actually works now) so a major rollout of this client would probably be unnecessary.  Citrix even state on the notes for this release “Any known issues in Version 12.1 of the product, except for the specific issues resolved in this private online plug-in, still apply.”  Those known issues can be seen here:

Oddly, the old broken client is still the main plug-in to download – you need to logon to MyCitrix to download the working version.

Installing XenApp 6 Hotfixes

Until Citrix release a proper service pack for XenApp 6 (I’ve heard this might still be months off), having your Citrix hotfixes up to date is really important.  Frankly, there are some killer bugs in the initial release of XenApp 6 – luckily the patching system works well.

Download the Hotfixes from here:

I build my servers using Altiris, but I have found that using Altiris can be an unreliable way of installing Citrix hotfixes.  Instead I now have a file share with the hotfixes in, together with a batch file that installs them all in one go and then reboots once at the end.  Rebooting after every hotfix is not necessary, although the order they are installed in can be important. 

The script I use is adapted from one written by Paul Johnson which I got from the forum below, so all credit to Paul for sharing this:

Note that the script I use does not install every hotfix Citrix have released – some fix issues I have not come across yet, others are for other versions or languages only.  Therefore, this might not be a complete script for you – its worth looking at the other hotfixes on the Citrix site.

Anyway, this is the current script!

I save the script in the same folder as the hotfixes called “installall.bat”.  On a single server I build I’d just run this manually from the console, with a lot of servers to build I would use Citrix’s new Installation Manager (which is basic, but it does work…) to create a new schedule – for instance:


Obviously if a single new update comes out I can then create another batch file to just install that one and reboot, then set Installation Manager to do the whole farm out of hours.

Note that you can then use the Delivery Services Console to find servers which are lacking hotfixes.  To see the servers at a glance…

  • Launch the Citrix Services Delivery Console (installed on manually built servers by default)
  • Set your farm connection up if needed
  • Click your farm name under the XenApp link on the left
  • Select the Hotfix Summary tab
  • You should now see all your servers, along with a useful count of hotfixes installed


If you then find a server which is missing hotfixes in the Servers section and click its Hotfix Details tab, you should see a list of the installed hotfixes.  So for the server above with only two hotfixes installed, I can go to it and see this is very out of date!


Note if you want to search for a server missing a specific hotfix, Open the DSC, click Search, and select Servers without hotfix:
