[Client] Unable to launch LoL client

jubilee·Feb 13, 2016·5 votes·2,042 views

I cannot launch the LoL client. The black and gold League of Legends symbol flashes up briefly but nothing happens after that.

I have tried the following:

running lol.launcher.exe as an administrator
running lol.launcher.admin.exe as an administrator
restarting my computer
uninstalling and reinstalling League
reconfiguring my firewall
deleting the lol_launcher folder and relaunching Edit:
I have also tried disabling Avast to no avail (going to try uninstalling now)

I also do not see League running in my task manager.

Nothing has worked. I don't even understand what kind of problem I'm facing. It's rather frustrating.

Update: I reinstalled it in a new location. That seems to have fixed whatever problem it was having. I'm not even sure what caused the error in the first place but this is a retarded fix.

Found issue is Avast resolved by excluding from quarantine chest

I tried disabling Avast and ended up uninstalling it so now I have no security or firewall. It still doesn't work.

Same thing here, someone found that it's really Avast causing this?

Found how to fix it without reinstalling

Right click on the avast icon in your task bar.
Select Quarantine Zone
Right click on lollauncher.exe in the list of quarantine files.
Select Restore and Exclude
When prompted replace the luncher

tadam!

I have the same problem. Avast will not let LOL open. Says it contains malware. I also have tried running as admin, uninstalling, reporting as a false positive and disabling Avast. I have 2 computers and it is the same issue with both. Both are HP with Windows 8 OS. WTF?
