[c++] How to fix the error "Windows SDK version 8.1" was not found?

I installed the 8.1 SDK's version:

https://developer.microsoft.com/en-us/windows/downloads/sdk-archive

It used 1GB (a little more) in the installation.


Update October, 9. There's a https error: the sdksetup link is https://go.microsoft.com/fwlink/p/?LinkId=323507

"Save link as" should help.
