I’m experiencing some problems with the following issues:
1) How to know what is the TeXlive version I’m using, and how to know if it’s the latest one;
2) How to update it in case it’s not updated (provided it’s worth doing it, rather than remove the older version and install the up-to-date one);
3) How to install a package that is not contained in the downloaded distribution.
As for the first question, what I do now is to type
tex --version
in the command prompt, and I get something like
tex --version TeX 3.14159265 <TeX Live 2015/W32TeX> [...]
But I don’t think that’s enough…
As for the third one, I read about it but I haven’t been able to make the packages work. I’ve read what’s written in here and the package I’m looking for is – according to tlmgr – already installed… (Obviously pdflatex doesn’t find it).
Thank you very much for your time.
PS I use Windows 8.1
