Compiling my .tex files gives me errors such as missing the required styles and libraries. For example like this:

Pdflatex: security risk: running with elevated privileges
This is pdfTex, Version 3.141592653-2.6-1.40.24 <MiKTeX 22.3> <preloaded format = pdflatex.fmt>

<C:\ Program Files\MiKTeX\tex/latex/base\fontenc.sty
Unfortunately, the package Cyrillic could not be installed.
Please check the log file:
C:\Users\  B  \AppData\Local\MiKTeX\miktex\log\pdflatex.log

Package foentenc Error: Encoding file ‘t2aenc.def’ not found.

Therefore, I've tried to install such libraries separately. The MiKTeX has (https://miktex.org/packages/markdown/files) different additions for perfect compilation of different types of files and libraries usage. But I didn't find how can I get them (github suggests from different authors) How can I get .sty separately?

  • It's probably easiest to use the package manager that comes with MikTeX, i.e. the MiKTeX Console. Downloading from CTAN is another option, but is generally a little bit more difficult.

  • You should install them in aLocalTeXMF directory, respecting the structure of a TeX directory, and you declare it through MiKTeX Settings.

  • I think I should re-install my MiKTeX, because it cannot install packages even from the console mode with administrator rights. It always shows the SSL connect error Aug 15 at 8:02
  • That SSL error might just be a bad mirror with an expired SSL cert. You could just choose a different mirror.

  • Try TeXLive, by default make a full installation and therefore take some time, but after that, very rarely you will need download anything else. The bad news are that packages are upgradable only for some moths, them the year version is frozen, and you must to expect some time to install (better that upgrade) the next version, but once installed properly, no problem of downloads at demand.
