Unable to start the minecraft runtime environment. This is most likely caused by a corruption. Please try to reinstall minecraft. After I uninstalled minecraft and re-downloaded, it happened again even after multiple tries.
1.Just triggers as soon as I download the runtime. It installs completely and says "Unpacking Launcher." After it finishes that, it crashes and says Unable to start... etc. etc.
