The Citrix client allows you to use Windows tools (Medewerker button, MS Office) on Linux and OSX (even from home!).

The WUR Citrix site lives at , you can login with your WUR account.

Installation of clients

Debian Linux

(NOT icaclient 12.1 on 64 bit Wheezy - see below this section)

Select the Debian package (.deb extension) from the Citrix site. Download it and, for example

 sudo dpkg -i icaclient_12.0.0_i386.deb 

If install fails because of unmet dependencies do:

 sudo apt-get -f install

Now the certificates may not be found, resulting in a 'Addtrust External CA Root' not allowed (61) error. Copy the Mozilla certificates in place with

 dpkg -L icaclient | grep keystore/cacerts  # check locations
 sudo cp -vau /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts

Now it should just work (tm).

To modify the desktop that it does not take full screen edit the file /opt/Citrix/ICAClient/config/All_Regions.ini and edit the section to contain

 [Client Engine\GUI]

icaclient 12.1 on Debian Linux Wheezy 64 bit

Unfortunately the icaclient 12.1 package provided by citrix has multiple issues under debian wheezy x86_64:

- unresolvable dependency on ia32-libs (not available under wheezy) - unresolvable dependency on nspluginwrapper (not available under wheezy) - bug in postinstall script leading to unrecognized architecture

to resolve the first two issues in a quick-and-dirty way we can add the squeeze repository to the apt sources by adding the following line to /etc/apt/sources.lst

  deb squeeze main contrib non-free

and then doing:

  sudo aptitude update
  sudo apt-get install ia32-libs
  sudo apt-get install nspluginwrapper

Of course you know that *bad things* happen if you mix packages for different debian versions (, so you may want to compile these packages yourself instead (which is broken)

After this, you have to repair the postinstall script in the icaclient 12.1 .deb archive:

  mkdir temp
  dpkg -x icaclient_12.1.0_amd64.deb temp
  mkdir temp/DEBIAN
  dpkg -e icaclient_12.1.0_amd64.deb temp/DEBIAN
  <yourfavoriteeditor> temp/DEBIAN/postinst

now search for the function UpdateMachineHWSuffix (around line 2641) and change the lines:

       echo $Arch|grep "i[0-9]86" >/dev/null
       if [ $? -ne 0 ]; then


       echo $Arch|grep "i[0-9]86" >/dev/null
       if [ $? -ne 0 ]; then
               echo $Arch|grep "x86_64" >/dev/null
               if [ $? -ne 0 ]; then

after this you can package your modified package and install:

  dpkg -b temp
  sudo dpkg -i temp.deb

IF you made a mistake OR IF you previously tried to install the unmodified package and got an error, then you may want to purge the icaclient package first (otherwise you may keep getting errors):

  sudo dpkg -P icaclient

Now you should have icaclient installed, and you can proceed with installing the certificates (see section above)

After completion of the installation you can visit the website mentioned above, and the apps should "just work"


Install the Citrix receiver from the Citrix website.

Then start the browser, visit the citrix site mentioned above and ... that is all. It even works from home!

Using Citrix Applications @WUR

Medewerker button

Start Citrix.

In the Library64 folder click on Desktop Library, this will open a Windows 7 desktop.

The Medewerker button shortcut can be found in

'W://APPS/MyData/Medewerker button HRM'

To get there, click subsequently on :

Start -> Computer -> Network Drive (W:) -> APPS -> MyData

If you scroll down in that folder, the "Medewerker button HRM" will show up.

Here is a screenshot of how it looks :

"Medewerker button screenshot"

You could also try to get there from the Citrix Applications tab, by clicking subsequently on :

Office -> Explorer

and then click subsequently on :

Computer -> Network Drive (W:) -> APPS -> MyData
