BrowserStack Live is exclusively designed for website/webapp testing across various platforms including Windows & MacOS. Given this, within Live sessions, we minimize providing functionality which do not relate to the browser or to website testing. Hence, installing native applications on Windows or MacOS platform is not supported.
However, we do offer another product – App Live – which is a native mobile app testing tool, wherein you would be able to install and test native mobile applications if that is a requirement. For more information, please check – https://www.browserstack.com/app-live.
