If you have Real Player installed on your computer, and you have a Zune device or Windows Phone, you’d probably see the following error message when trying to sync your device:
RealDownloader is using your device. To see sync status, close that program
Though the recommended solution in the error message is asking us to close the program, time and again, people wonder which program to close as there’s no real instance of the Real Player running. So, what should you do?
Simple – just open Task Manager, go to the ‘processes’ tab and look for ‘recordingmanager.exe’. Just right-click on it and hit ‘end process tree’. The status on Zune will change immediately, and you can sync your Zune player or Windows Phone right away. Hope this helps!
