Thanks for your link, johnd, but it did not help.
It says an update for the driver was released last march -v6.7.3 dated March 3, 2016- but in the Silabs link the version to download is still 6.7.2.
I tried to download data from the weather station with another computer with Windows 10 build version 10.0.10586 and it worked perfectly, but with the other computer with version 10.0.14393 it does not work.
The option to roll back to an older driver version does not work either as the roll back button is greyed out.
