I was able to install Cisco AnyConnect Client on the Fujitsu Zero client, running Windows 7, 32-bit. However, after I get out of Fujitsu Zero client and to get back in, I got a blank screen and error message "Contact Administrator". Then, I Remote Desktop or Console to the Zero client to uninstall Cisco AnyConnect client. Then, I was able to get back in using my Fujitsu Zero Client. Looks Cisco AnyConnect client overwrote some of the Zero client files. Have you experienced this problem? Do you have any suggestions? Please let me know if you need additional information or have any questions.
