Cannot launch Minecraft 1.12.2 on two separate computers - both windows 10. Attempts to start using a specific user profile results in message "java(tm)platform se binary is not responding". When closing that message, the launcher attempts to launch again. If "play" is selected, the same message appears. However, can launch 1.12.2 from another PC using a different user profile Have also encountered the message that there is another instance of Minecraft running on the server when only one PC is operating in the home. Attempted to resolve by: Reboot Restart Delete and re-install (daughters PC) Cleared JAVA cache Updated JAVA Would appreciate help to resolve.
