In the past, simply extracting the offline installer from will net you a working Java installation. For me however the bundled runtime is simply too out of date, a lot of mods will display warning about bugs specific to the earlier versions.įinally, the idea of installing the official Minecraft launcher just to use it’s bundled runtime with MultiMC just seems strange to me. Thankfully, Mojang have bundled Java runtime onto the official Minecraft launcher. It would come with a control panel applet, a web browser integration, an annoying updater, and worse of all: a toolbar ads on the installer itself, all of which is not necessary to play Minecraft at all! One of the most frustrating aspect about installing Java to play Minecraft is that the installer would try to integrate Java onto Windows.
