I am trying to delete an old version of iTunes installed in Windows 10. Deletion has been unsuccessful using the iTunes app and using Control Panel. One reason for this is that mdnsNSP.dll needs to be deleted but cannot be deleted because Windows 10 reports that it is open in Radeon Settings Host Application. I opened Radeon Settings but have no idea how to go about closing mdnsNSP.dll . Need help with this! Thanks in advance.
