I know that FlexViewer apps are old, but I need to migrate the app from a Windows Server 2012 server to a Windows Server 2016 server. I copied the crossdomain.xml file from a Windows Server 2012 to a Windows Server 2016 server but I get a 404 error in the app and a page not found error when I navigate directly to the xml file in a web browser.
Has anyone been able to get a FlexViewer app working on a Windows Server 2016 server? If so, would you have any idea what I am missing in my setup?
