I write my reports with LaTeX. I use TeXmaker plus TeX Live distribution. I want to use XyMTeX in a document when I wanna use \usepackage{xymtex} but there are errors. I don't know anything about how to install a new package. I'm new to LaTeX but I'm well experienced with Windows

    @Jasper ... except that xymtex isn't free (in the sense of "air", at least) so isn't in tex live. xymtex is a marvel (and all that) but it's big and unwieldy and difficult to "keep up with"; there are real chemists around here (i was last a chemist in 1965...) -- they might be able to suggest something better.

  • I'll be grateful if someone suggests any other better package or bundle. Thank you jasper Loy.

  • I haven't used this package before, but I did look at it for some of my drawing ctan.org/pkg/chemfig. There is a brief tutorial/example at this location as well: mychemistry.eu/2011/11/a-small-exercise

For me, installing XyMTeX worked well enough using the .zip file containing the latest version. What I did:

  • Download the .zip file
  • Extract it
  • Copy the entire contents (xymtex folder) to my local TeX tree. On Windows with TeX Live, that is %USERPROFILE%\texmf (Linux ~/texmf, Mac ~/Library/texmf).

The .zip file contains the code plus source, but as it works without further unpacking I would just use as-is. Following the above steps, the simple demo


works fine using pdfLaTeX. (Note: the XyMTeX manual has xymtxpdf as the package name, but this seems to be erroneous as the file is called xymtexpdf.sty.)
