1.  Source code

The sources of the current LyX release can be found here (also in tar.bz2 format). If you don't know what source code is, see the article in Wikipedia.

2.  LyX installers (binary versions)

Binary versions of LyX for installing in different operating systems can be found below.

2.1  Windows binaries (2000/XP/Vista)

The standard installer can be downloaded here: LyX-1.5.5-3-Installer.exe
The alternative installer here: ftp://ftp.lyx.org/pub/lyx/bin/1.5.5

These installers will setup a complete LyX environment. For more information about Windows downloads, see our wiki page.

2.2  Mac OS X binaries

LyX for Mac OS X is available here: 1.5.5-Universal. Before you install LyX you need to install a TeX system such as MacTeX.

Make sure that you run the LyX-installer provided in the disk image, and see the LyX/Mac wiki page for further installation tips.

2.3  Linux binaries

Major Linux distributions take care of LyX binaries themselves and you will find LyX in their repositories. Some people are kind enough to prepare deb/rpm packages for latest versions. These packages are not officially supported by the LyX Team though, and if you experience problems, please try the official source distribution. For more details look in our wiki.

3.  Additional Software

If you're not using one of the installers or packages, you may need to install some additional software.

4.  Version numbers

There are certain rules how the LyX version numbers are assigned. Read the following page for detailed information.

5.  Previous versions

6.  Mirrors
