As I dare say Steve knows, but for anyone else who may be interested,
the necessary USB Virtual Com Port (VCP) 'driver' is actually provided
by Silicon Labs ('SiLabs') because they're the people who make the
chipset that performs the protocol conversion. If you're having
trouble getting this to work eg because of an unusual PC configuration
then there may well be a more recent or more relevant driver version
on the SiLabs website at:

https://www.silabs.com/products/mcu/...CPDrivers.aspx

Davis tend to include a new VCP driver version in their CD or download
libraries only once they've had a chance to test it thoroughly with
the Weatherlink loggers, which can obviously be a good thing (TM) but
does mean that the Davis version will not necessarily be the latest
available.
