There are 2 Windows installer variants:
- Bundle: LyX-221-Bundle-2.exe (~255 MB)
Download this one if you are a new user. It installs a fully functional and complete LyX setup including a LaTeX distribution and a bibliography manager. (GPG signature)
- Installer: LyX-221-Installer-2.exe (~49 MB)
Download this one if you already have an older version of LyX installed and you want to update it. This installer requires that LaTeX (MikTeX or TeXLive) already be installed. (GPG signature)
A binary for Cygwin can be downloaded here: lyx-2.2.1-cygwin.tar.gz.

Although we had previously announced that the 2.2.x series would no longer support Windows Vista, contributions from our users have made it possible for us to do so. So LyX 2.2.1 does run on Vista.
For more information about LyX for Windows, see our wiki page.
LyX for Mac OS X is available here: LyX-2.2.1+qt5-x86_64-cocoa.dmg, and the GPG signature is here. (There is also a package for some older systems: LyX-2.2.1+qt4-i386-cocoa.dmg, with the GPG signature here.)
Before you install LyX you need to install a TeX system such as MacTeX.

On Mac OS X Mountain Lion you'll get the error message: "LyX" can't be opened because it is from an unidentified developer. See the explanation here for a work around.
See the LyX/Mac wiki page for further installation tips.
Major Linux distributions take care of LyX binaries themselves and you will find LyX in their repositories. For more details about your distribution look in our wiki.
For Ubuntu users, Liviu Andronic maintains a stable PPA (Personal Package Archive) and a daily PPA which contain up-to-date versions of LyX. See the LyX on Ubuntu wiki page for information and instructions.
The versions of LyX on a variety of Linux distributions (as shipped with the vanilla distribution) can be seen on the snippet below. Note, however, that most distributions provide newer versions than the listed ones via upgrade services.

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

To verify a tarball with GnuPG, do this:
gpg --recv-keys 0xDE7A44FAC7FB382D
to receive the key (only needed once), and
gpg --verify lyx-2.2.1.tar.gz.sig
to check the signature (or any other signed file you want to verify). Watch out for the "Good signature..." string.
