Get the latest Jalview desktop application:

  • Alternately, download an installer for your system from the InstallAnywhere Jalview Installers page.
    InstallAnywhere is a Java program installation system. It will work out which operating system you have, and present you with the package it considers most appropriate. You can download the Jalview application installation on its own, and optionally download a copy of the Java Virtual Machine which actually runs Jalview.


Installing on OSX

We recommend you install the jalview desktop via a signed OSX disk image: Install Jalview + Java or Install Jalview only.

It is also possible to launch Jalview on OSX via Web Start, but you will first need to either modify your GateKeeper security settings (see the FAQ entry), or open a Terminal and enter


This works because webstart launches from the commandline appear to bypass the GateKeeper security warning about "unknown developers".

More about running the Jalview application

If you don't have Java version 1.6 or later, first install Java on your machine from from the Java Download Site. Then click on the Install link above.

If your browser hasn't been set up to run Java WebStart JNLP files, the Start link above will download a file called jalview.jnlp. Some browsers will ask you what you want to do with the JNLP file (instead of automatically downloading it somewhere, or presenting it to you as text). If a dialog appears with "Open using application..." on it, use the javaws application to run your file (and check the box marked "Don't ask me again"):

  • <path to java runtime installation>/bin/javaws
  • <path to jdk installation>/jre/bin/javaws
  • javaws.exe

If you think that your browser should really be working with Java properly, you can test it at If things really are not working, use the InstallAnywhere version of Jalview.
