I have a question, that may have been answered somewhere else but my search in Slack didn't turn up. Is it possible to set the launch.ica file to launch automatically without the user needing to interact with it? I know the user can right click and indicate to always open files like this, but I'm trying to take that element out of the equation for logon times. (Also, the security side of my brain is asking if I really want to do this?)

yes you can. We do it this way. In the chrome gpo we have the setting list of file types that should be automatically opened on download. that gpo is set to ica and then to add a little more security we have set the urls where autoopenfile types can apply to our netscaler gateway
