Adobe Flash-based applications will no longer run as of January 12, 2021. As a result, the original StreamCatcher software is not currently functional and is no longer available for download. StarTech.com has replaced the previous Flash based software with the new StreamCatcher Pro which is now available for free under the Drivers/Downloads section of all supported capture device product pages. Please uninstall the original software and download/install the new StreamCatcher Pro to continue using your StarTech.com capture devices.
More information about Flash support being discontinued is available here from Adobe.
