Given the path returned by the first error trace, I imagine that one is due to file permissions trying to write to C:\Windows. This would imply that perhaps the test isn't running where it thinks it is? Running the same test in isolation with GoLand returns the following which I think supports this:
GOROOT=C:\Go #gosetup
GOPATH=C:\Users\chris\go #gosetup
C:\Go\bin\go.exe test -c -o C:\Users\chris\AppData\Local\Temp\___TestDirsSearch_in_github_com_spf13_viper.exe github.com/spf13/viper #gosetup
