Hi there. This is strange. Can you please ensure the server is shut down and then restart following this guide: [How to start and stop Wowza Streaming Engine software](https://www.wowza.com/docs/how-to-start-and-stop-wowza-streaming-engine-software) Be sure to also start the Engine Manager. If this does not work, then try uninstalling and reinstalling Wowza. If still no joy, please open a support ticket by sending an email containing a zipped copy of your /conf and /logs folders to support@wowza.com Regards, Salvadore ---

Installed on a different machine and it worked fine . Although recorded files have lot of green frames and video looks terrible . Do I need to make any additional settings that I might be missing ? ---

Are you testing the sample file with a sample player that ships with Wowza? Salvadore ---

This could be a java issue. I suggest uninstalling and re-installing java on your machine. You can follow this guide for more information and troubleshooting steps: [How to manually install and troubleshoot Java on your Wowza media server](https://www.wowza.com/docs/how-to-manually-install-and-troubleshoot-java-on-your-wowza-media-server) Regards, Salvadore
