Hello!
Downloaded, started the installer (whilst previous version was still running)... nothing happened.
Exited Maxthon, ran the installer manually & that installed ok, but instead of restarting, there was a brief white screen, then exit.
Tried running again, same.
Checked Task Manager to make sure Maxthon not running at all (wasn't) & ran again & this time it loaded ok, but didn't show the changelog (checked mx://mxupdate & there's a spelling mistake: "canceled" should be "cancelled")
