LiveEdit can be downloaded from the SourceForge project page. Alternatively, you can jump right to the latest release.
Windows 95/98/NT users will also need to download the required Rich Edit Control library. This library only needs to be downloaded once and will not change with future releases of LiveEdit. Installation instructions are included in the zip archive.
