If you want to launch the Jagex Launcher / RuneLite through Steam while keeping features like hours tracked and Steam messaging enabled, here’s how you can do it:

Open Steam and right-click Old School RuneScape in your library.
Select Properties > Launch Options.
Enter the following line into the Launch Options box:

"C:\VideoGames\jagex client\JagexLauncher.exe %command%"

Make sure to adjust the path to where you installed the Jagex Launcher. This setup allows RuneLite to launch instead of the default Steam client for OSRS.
