Answer 1

I experienced this error today on windows 10, and the outputs you included are as good as identical to those of mine.

Neither J_F's workaround or adding "c:\Rtools\bin" to paths through advanced system settings solved it.

What solved it for me was to uninstall Rtools and reinstall it, checking the option to change the paths during installation. I put the paths: "c:\Rtools\bin", "C:\Rtools\mingw_32\bin", "C:\Program Files\R\R-3.3.1\bin\i386" and "C:\Program Files\R\R-3.3.1\bin\x64" in there.

I wonder why adding "c:\Rtools\bin" to paths through advanced system settings didnt change the output of Sys.getenv()['PATH']
