Issue installing on windows, built with msvc

[Fabrice Leal]

took a second look at this and turns out "nmake" was not completing
correctly... there was an error about not being able to spawn process "rc",
and apparently there's some issue about the VS2015 command line not having
it in the PATH. So I gave it another try with the VS2017 command line and
now it compiles and installs fine.
