Native Citrix Automation - Throws Error:Cannot automate remote app

I am trying to automate the app via native Citrix automation, but I am unable to do that.
I have a few questions regarding the same:

1)Install UiPath Remote Runtime in Citrix Application Server, But where do I get this for community edition?
2)I see it is currently available for the enterprise edition. I tried to request for community edition but no response from support?
3)Where will I get .exe or MSI installer?
