Help! upgraded from V2 to V3 and Sonarr wont launch

[Chris_Clark]

Hi, i have upgraded to to v3 and i can not login to the sonarr GUI.

Any help would be great.

Either Sonarr is already running or NZBDrone is still installed and already running

or your didn’t run as admin to start? but likely the second option - you never uninstalled v2

Hi, how do i check if NZBdrone is still running? ive looked in programmes and cant seem to find it. I see Sonarr V3 is installed
