Windows Scream Receiver comes with installation scripts to install and uninstall it as a system service. These scripts require administrative priveleges in order for the app to set it's priority level to Realtime. To install, run the install_task.bat script in the latest release.
During installation you will be asked for a port to listen on. This will be the active port for multicast streams on group 239.255.77.77 and unicast streams on local interfaces on the selected port. The default is 4010.
