"I am having problem in generating pdf output . I have downloaded , installed, checked tinytex, which says "TRUE". Tried various options suggested. Even specified path too. But it gave me error saying no pdflatex. I also downloaded latexmk and run it. But still it says no pdf latex. Any suggestions/help please. I am using PC.

You might be interested in reading through the conversation in this issue on the tinytex GitHub repository, https://github.com/yihui/tinytex/issues/103, which seems to be about something very similar to what you are experiencing.

It looks like some people (but maybe not all) ended up solving the problem via tinytex:::install_prebuilt(), but there were some other suggestions that you might want to try before you get to that point.

@aosmith Thank you so much. I run the prebuilt and tested exactly in the sites.
Now I can see pdf latex and seems ok. But, there is another error now.

"Error: Failed to compile X.tex.
In addition: Warning message:
In system2(..., stdout = FALSE, stderr = FALSE) :
'CreateProcess' failed to run 'C:\Users\X\AppData\Roaming\TinyTeX\bin\win32\pdflatex.exe -halt-on-error -interaction=batchmode "X.tex". "

Any idea what it says for? I am bit unfamiliar with error language

thanks

Well, I'm glad you made a little progress even if things aren't fixed.

I've never seen that particular error message. Searching the "'CreateProcess failed to run" portion of the error had a few hits but they involved slightly different message (like here) and don't look entirely relevant.

Hopefully someone else will be able to come along and point you in a new direction!

Hi,

I had the same issue and the tinytex:::install_prebuilt() fixed it for me!
