Parsec runs a system service to capture Administrator-level screens, like Task Manager. If you're getting a 14003 when connecting to your host, it's because the Parsec Service has been stopped. This happens when you terminate the Parsec process at some point. To confirm that the Parsec Service is running, visit Task Manager on the host, click services, and find Parsec. Please Start the service and then right click on Parsec in the task bar and restart it.
