Problem Cause

There can be a number of reasons for the issue including but not limited to:

  • The Internet Explorer browser option?? "Do not save encrypted data to disk"?? is selected in the Internet Settings on the Advanced tab.

  • A lockdown issue occurring after an upgrade of?? the current Internet Explorer browser version is preventing the launch.

  • The Web Interface server is not configured with the proper address routing or network address translation setting causing the launch.ica file to render with the incorrect local network IP address or https/SSL WAN address location.

  • Third party web browser based applications, known as Adware, or password caching shopping based programs installed on a client’s machine have been known to be the cause of this prompt.

  • The Citrix MIME types may not be configured correctly with ICA.


Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
