RNW file: "Compile PDF" button fails after MiKTeX update

(I was not aware that tinytex can be "enabled" for RStudio without changing PATH system-wide, as it's the case with tinytex::install_tinytex() .)

This option does not activate TinyTeX, as the distribution you get when doing tinytex::install_tinytex(). It will make RStudio uses tinytex the R package as rmarkdown does.

Interestingly, in the stable version of RStudio enabling the tinytex option seems to have no effect. Even the output remains "Running pdflatex.exe on test.tex...failed" instead of "Compiling document with tinytex ... completed" as printed by the daily build.

This is because the daily version fixed an issue with that. So for now you need the daily.

You can share in the rstudio issue what works for you maybe.
