On nwzCitrix you can use Windows software available in the NWZ from any terminal device with network connection (if necessary after VPN dial-in).
To use the applications, you need the Citrix Receiver. It installs a plug-in in the web browser. The following browsers are supported: Internet Explorer 6.X (or higher), Google Chrome, Mozilla Firefox or Safari. Supported operating systems on the device are Windows, Mac OS X and Linux, but also iOS, Android and ChromeOS.
In the Citrix Receiver application the desktop is located under "All Apps" and not on a separate page like on the website!
For mobile devices you can find the Citrix Receiver in the respective App Store. You must enter https://nwzcitrix.nwz.wwu.de as the configuration address.
Important: Outside the university network you need a VPN client. Further information can be found here: VPN instructions
