The configuration script cannot find Windows SDK

EncVar

I have downloaded Windows SDK correctly, but the script just can't recognise it.

Which script? Did you properly open the visual studio command prompt so all is correctly set up?

I did follow the instructions to set up my environment correctly.
And here's the output of the configuration script:
