Hi All,
I have newly installed RStudio version 3.3.2 on my system and is trying to use RMarkdown in R, but I keep having the message below;

I have installed MiKTeX 2.9.6361 on my system before opening the RMarkdown project.
I see that there is rmarkdown 1.6 version, so I deleted the version 1.1 on my system and re-installed it again, but each time it's the version 1.1 that keep instaling. My CRAN mirror is set to "Global (CDN) - RStudio".
Can anyone point me in the right direction on how to resolve this problem, please?
Many thanks.
