To run Synthclipse you need:
Synthclipse runs on all three major desktop Operating Systems:
You can download the latest version, in form of prepacked Eclipse with Synthclipse feature, from Synthclipse's SourceForge website. Remember to chose proper version for your Operating System and CPU architecture.
Alternatively you can install Synthclipse from an existing Eclipse instance using the following Update Site: https://kamil-kolaczynski.github.io/synthclipse/update/.
Prepacked version has one advantage over the update: it has nice console logs coloring since it shipped with Grep Console plugin that is specially configured for Synthclipse logs.
Installation is very simple. Just extract downloaded archive and run file eclipse.exe (or just eclipse depending on your Operating System).
