I have Winflector server v4.0.3.1 set up, but when I attempt to launch an application via Winflector Virtual Terminal v1.1.4.3, I get an "Error 53: Server does not respond" message.  (It does, however, launch a background process of the application that can be seen in Windows Task Manager.)  What could be causing this error, and what can I do to resolve it?

Thanks for the logs. We'll look into the application's inability to launch issue. However, even if we manage to fix this issue, another issue remains: Winflector doesn't support audio or video streaming. Therefore, the application you're trying to launch likely won't work properly. Regardless, you should be able to launch the application and it should work until you start a video.
