PortInUseException: Port 8989 is already in use

I just upgraded from Windows 7 to 10 this morning.

Since the upgrade, I have not been able to start Sonarr. I keep getting an error

“PortInUseException: Port 8989 is already in use, please ensure Nzbdrone is not already running.”

I do see the nabdrone.exe task running. I close it. and do it again, same error. I have uninstalled and reinstalled Sonarr, same error.

I have no idea what to do. Please help!

Try running it as administrator, if that doesn’t work post the full log.
