Return of Reckoning

Hi guys, im new here and I download the game and follow the steps but, when I put my pass and nickname in loucher, apears error like this:

Error Downloading updater:
System.UnauthorizedAccessException: Acceso denegado a la ruta de acceso 'D:\Descargas\ReturnOfReckoning-March2020\Warhammer Online - Return of Reckoning\RoRLauncher.exe'.
en System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

en RoRUpdater.MainWindow.tYB114Sxk(Object , DownloadDataCompletedEventArgs )

Anyone know how I solve this?

Remove write protect on all game files and subdirectories
Also check torrent is turned off

Thanks Acidic, is working now
