Pointing ADaudit to MS SQL server

The instructions in Help in ADaudit say "Please install the corresponding SQL Native Client & Command line Utilities in the ADAudit Plus machine as per the SQL version and CPU type of ADAudit Plus machine." This is for a Remote MS SQL server, so which version are we to use?

Also, under that section it says "Note: After clicking on the above Download link, in the Microsoft website, please click on 'Install Instructions' and Download." When we go to Install Instructions, there are over a dozen different things to download there, which one( s ) are we supposed to be downloding and installing?

The documentation for this product is terrible!
