ERROR: Your game version is not supported by RAGE Multiplayer – how to fix it?

What to do if, when launching the RAGE Multiplayer launcher, which is an addition to the GTA V game, a window appears with the error “ERROR: Your game version is not supported by RAGE Multiplayer; Please update to…” – as the information itself indicates, your game version it is out of date with the version that RAGE Multiplayer supports and you need to update GTA V.

To update the game, all you need to do is start the Steam client, Epic Games or Rockstar Games Launcher and update the game – most often there is an “Update” button instead of the “Launch the game” button.
