Attempted upgrade from 15.3.1 to 15.3.2 on four of our twelve hosts. Identical problem on all of them so far - Serv-U.dll. "An error occurred while trying to replace the existing file: DeleteFile failed; code 5. Access is denied.
Have tried waiting & click "retry". Not happening. Went in & made sure service is stopped. Tried shutting down Serv-U first & exiting tray before attempting upgrade. These are very standard host servers, doing nothing other than hosting Serv-U. Are there any other customers running Serv-U host on Windows that have successfully upgraded to this version?
