Retrospect requires SQL-DMO components that are not automatically installed with SQL 2008 and later. Without the required Microsoft configuration, Retrospect will report authentication failures when trying to license the databases under Configure>volumes.
To fix the problem, users need to download and install the "Microsoft SQL Server 2005 Backward Compatibility Components" package to the Server running SQL Server 2008 and later.
Contact Support for a download link for the x86 installer or the x64 installer, depending on your configuration.
Install the Microsoft SQL Server 2005 Backward Compatibility Components.
Open Retrospect and go to Configure>Volumes. Right click on your SQL server and select License to apply your SQL license and authenticate to the server.
