I can't open the laucher for awhile now, and it started to trouble me. I tried to reinstalled it and it only opened a 'repairing' window, make me wait a long time, and it disappeared, which returned to the problem i'm having. Everytime i tries to open it, the logo appears, disappears, nothing happens. Can someone tell me how to fix this?
PrisonNightmare1 votesGo into Task Manager and make sure the league client still isn't open in there.

PrisonNightmare1 votesMake sure you close out ALL things related to LoL in the task manager, not just one process of it. But other than that I'm not sure, I'd try making a ticket and contacting Riot Support that way.
