Hi Luke, Apologies for the issue you encountered with the agent installer download via controller wizard. Could you please let us know the SAAS controller URL so we can check for the download issue in that. Also, if you are able to download the agent installer from https://download.appdynamics.com/download/ URL, you can try the agent installation as per https://docs.appdynamics.com/display/PRO44/Install+the+PHP+Agent+by+Shell+Script documentation. Please let us know if you still encounter any issues and we will assist further on that. Best Regards, Piyush
