We only provide support on this forum for stand-alone installations. Installations based on softaculous or custom software of your provider is not possible to be supported as we have no knowledge about this.
So either you need to contact Dewlance support for your specific site, or if you have FTP/MySQL access to your installation you could install serendipity on your own, independently from what your provider provides you...
