- How to install 64bit binaries for TeX Live on Windows
-
-
-In the following, $INSTALLDIR is $SELFAUTOPARENT in the TeX Live,
-that is, the parent directory of "texmf-dist". Actually the
-directory $INSTALLDIR is shown by a command:
-
- kpsewhich --var-value=SELFAUTOPARENT
-
-
-(1) Expand the file tl-win64.zip in $INSTALLDIR.
- In the case of update, remove all files in $INSTALLDIR/bin/win64
- before expanding tl-win64.zip, because it is possible that
- some files are deleted in a new tl-win64.zip.
-
-(2) After expanding tl-win64.zip in $INSTALLDIR,
- change related command PATH from
- $INSTALLDIR\bin\win32
- to
- $INSTALLDIR\bin\win64;$INSTALLDIR\bin\win32
-
- Note that the following 32bit binaries in $INSTALLDIR\bin\win32
- are still used on WOW64:
-
- gunzip.exe gzip.exe jbig2.exe latexindent.exe
- psviewer.exe tex2xindy.exe texindy.exe tlaunch.exe
- tlshell.exe unzip.exe xindy.exe xindy-lisp.exe
- xindy.mem zip.exe
-
- Moreover, tlmgr.bat does not exist in $INSTALLDIR\bin\win64
- due to an obvious reason.
-
- Thus $INSTALLDIR\bin\win32 is necessary "after"
- $INSTALLDIR\bin\win64.
-
- If there are problems in 64bit binaries, it is easy to recover
- the original TeX Live win32, by changing back the PATH:
- $INSTALLDIR\bin\win64;$INSTALLDIR\bin\win32 --->
- $INSTALLDIR\bin\win32
-
-(3) Ghostscript is assumed to be 64bit. The dvisvgm.exe searches
- for gsdll64.dll by reading registry, and gsftopk.exe searches
- for gsdll64.dll in the command PATH. Therefore users should
- install 64bit Ghostscript and set the command PATH for the
- Ghostscript. However, don't define TEXLIVE_WINDOWS_EXTERNAL_GS
- in texmf.cnf, because the preinstalled 32bit Ghostscript is
- also used in several cases.
-
- From TeX Live 2020, the version of 64bit binaries will be
- synchronized with that of 32bit binaries. It is expected that
- common format files can be usable for 32bit/64bit binaries.
