My name is Hunter Ellis, I run my High School's TV production and live streaming teams. CCleaner is one of my favorite programs that I have always stood by. I just wanted to give everyone a heads up on this little problem.
The "Tricaster" is a machine (computer) that we use for the TV announcements and live streaming. The Tricaster has a "Chroma key" feature for green screens. It also has a "live set" feature to make it look like you are in a professional studio.
The CCleaner registry cleaner seems to mess up these two features. It took me about 2 hours to figure out why they "just randomly stopped working" but after many tests I've found this to be the cause of my problem. So if you are working on any model of a Tricaster, I would not use the registry cleaner. All other features of CCleaner work just fine with Tricasters.
Thanks,
Hunter
