Launched beta league client fine after update. But then decided to close the client to login again, league client didnt launch so I opened task manager to shut down all the league clients. Tried launching league client again and received this error.

The only way I get anywhere is I can click the lol.launch.admin but when I click launch i get this error again, clicking repair also did nothing..

Thanks for all your help

I had the same problem after starting a normal, draft pick. The game crashed after the champion selection as the game starts. So I closed the game client and deleted the new launcher (and empty bin): LeagueClient.exe (new) lol.launcher.admin.exe (old) lol.launcher.exe (old)

Then I startet lol.launcher.admin.exe and was able to login. Next I run the troubleshooting tool in general options (top right in client). http://i.imgur.com/xDB7D06.png

This message came at the end of the repairtool. http://i.imgur.com/uuLGzyF.png

The client applied the new patch (~84MB) again and it worked.

Hope my english wasnt too bad and it helps you.

Yo guys, do you all have the new client,cause i do, and it probably has something to do with it. I went into the league file, and launched the legacy client straight from the lol.launcher.admin and it works just fine. Tell me if that works for you, hope it does.

It still works fine with the old launcher but nothing has changed for the new one. Still broken.

Same problem here, dunno what else to do. Repairing, using Hextech Repair Tool, rebooted PC. Nothing works. Will take some time for a Rioter to reply.

Hm..i get my client running again by: run an repair,move all one day old log files to a new location and then lunching LoL from c:\Riot Games\League of Legends\RADS\projects\league_client\releases\0.0.0.38\deploy\LeagueClient.exe

It installed some updates..then I closed it and i restarted the client the normal way...maybe it help for you too.

I was working on my client too. I got the Bug splat to go away... I feel like this won't be long before it comes back. I redownloaded the Alpha Client. Which is the beta. Except when the client load does not click update now. Click Download later. After that wait for it to patch. You want to download the older client because it's less buggy. BOOM! got it back, longest hour of my life for it to patch. BUT I GOT IT!

Yeah I had this same problem too, where this same menu popped up, and then i tried uninstalling and reinstalling. The old client worked, but then when I upgraded back to the new client is when I started having problems. It's never any use contacting Riot because it's NEVER their fault, it's ALWAYS something that YOU'RE doing wrong.
