Which Version of BusinessObjects.DSWS.*.dll?

Hi Folks,

We're running SAP BusinessObjects BI Platform 4.1 Service Pack 2, Version 14.1.2.1121.

Which version of the BusinessObjects.DSWS.*.dll files should we have?

The files installed on the server in this location: "C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win64_x64\dotnet\web services\dsws_consumer"  have a date of 10/10/2013 which seems too old.

Where do we find and download the correct version of these BusinessObjects.DSWS.*.dll files?

Thanks for any help.
