Hello, Have you checked it is in the PATH system variable? After installing Rtools you must edit the Windows PATH. It not, the system will still find the older Rtools version.
No, well as long as we are talking about base R, which we should be talking about on this list. R automatically adds Rtools to PATH when it is needed there. R knows which version of Rtools it needs (R 4.2 uses Rtools42, R 4.3 uses Rtools43, R-devel currently uses Rtools43 but that will change before R 4.4 is released). More details are in https://cran.r-project.org/bin/windows/base/howto-R-4.3.html Tomas
Hope this helps, Rui Barradas
