We currently only support the
official RuneScape Java client (and
RSU for our Linux users).
This client works for both RuneScape 3 and Old School RuneScape. If you are unsure if you have this version, uninstall RuneScape from your computer, download from the link above, and re-install. If you do not have it yet, download and install it. Please keep in mind that you must restart RuneMate after installing the RuneScape client.
