! pdflatex: warning: running with administrator privileges

! Sorry, but C:\Users\jjw11\AppData\Local\Programs\MIKTEX~1.9\miktex\bin\x64\pdflatex.exe did not succeed.

! The log file hopefully contains the information to get MiKTeX going again:

I got this error message while I was trying to generate pdf file using r markdown.

How can I solve this? I installed tinytex using install.packages("tinytex")

I also tried tinytex::reinstall_tinytex(). But I got this error message

tinytex::reinstall_tinytex()
Error in system2("tlmgr", args, ...) : '"tlmgr"' not found
In addition: Warning message:
In tlmgr(c("info", "--list", "--only-installed", "--data", field,  :
  TeX Live does not seem to be installed. See https://yihui.name/tinytex/.

I installed tinytex using "tinytex::install_tinytex()".

When I installed tinytex using "tinytex::install_tinytex()", I got warning which implies other Latex distribution was already installed.

I tried to generate pdf file after I installed tinytex using "tinytex::install_tinytex()".

But this time I got this error message.

Try other LaTeX engines instead (e.g., xelatex) if you are using pdflatex. For R Markdown users, see https://bookdown.org/yihui/rmarkdown/pdf-document.html

Do I have to uninstall other Latex distributions?

Then, how can I uninstall other Latex distributions?

Answer 1

I've solved my problem.

First, I had to install Tex distribution.

I could install Tex distribution by using tinytex::install_tinytex().

Second, I was using CJK(Chinese, Japanese, Korean) characters.

so I had to use different latex engine.

In addition, I had to set mainfont which contains my language(korea) in the YAML header.

I attach YAML header which solved my problem.
