[Tex/LaTex] Using different versions of TeX Live on Windows

lyxtexlivewindows

I have a Windows 10 computer with LyX 2.2.3 and TeX Live 2016 installed.

I then installed TeX Live 2017.

LyX is still using TeX Live 2016, but I would like it to use TeX Live 2017, and perhaps even switch back.

Is there a simple way to have LyX use a particular version of TeX Live on Windows?

Best Answer

Go to Tools -> Preferences -> Paths and change C:\texlive\2016\bin\win32 into C:\texlive\2017\bin\win32 in the Prefix for PATH.

I have the Italian version, I hope it's clear, anyway:

Of course, you can change that Prefix for PATH back to 2016, if you would like to use the previous version of TeX Live.

You must adapt the PATH-variable if you want to use the "other" system. This should work fine. I have a small TeX Live-like LuaTeX-system for testing and it can even share some roots with my main MiKTeX, MiKTeX doesn't complain about the ls-R-files lying around. The only problem I have is that I sometimes get confused and no longer know which system I'm currently using.

There are thousand of web pages which explain how to change environmental variables permanently. For the current command line window you can use something like this

set path=J:\MiKTeX2.9\miktex\bin;%PATH%

which will put the new path at the front of the path variable. To see the values of the variables use simple set.

If you working from TeX Live installed with .deb official Ubuntu packages, or you have not TeX Live installed, then you only need:

sudo apt-get install lyx

If you are working with TeX Live 2013 installed from the DVD or the with install-tl-unx.tar.gz, the anterior method is not convenient, because the lyx package dependencies, apt-get wish install also many texlive-* packages with a older version.

To solve this problem with LyX (or any LaTeX editor), you have two approaches:

Make a dummy texlive-local.deb package and install so that apt believe that all dependencies of lyx package already are satisfied, and you can install with apt-get. This is explained in Integrating vanilla TeX Live with Debian.
Download source code or a binary version of LyX and install in /usr/local

If PATH is correct, with both methods LyX will work without problems with the vanilla TeX Live. Although this is not as trivial as just run apt-get. Your mileage may vary.
