Prezados bom dia, ao tentar instalar o tinytex dá o seguinte erro:

Please restart your R session and IDE (if you are using one, such as RStudio or Emacs) and check if tinytex:::is_tinytex() is TRUE.
> tinytex:::is_tinytex()
[1] FALSE


Alguém sabe como resolver? Já procurei no google e não achei.
Desde já agradeço
