When I click "Launch" nothing happens.

So I click "Launch" and nothing happens. I restart my computer, finally make it to the login screen, and it says "logging on" for ages, then says can't connect to the server and closes out. I click the game again, click "launch", and guess what? Nothing happens. I restarted my computer once more and it did the exact same thing. Any help would be greatly appreciated!

I had the same problem recently with the 5.5.

Are you guys using any mouses configurator, I found mine actually blocked Leagueoflegends.exe (not joking, just did the test).

after trying reinstall/repair, restart computer and wayyy too many tips...

I'll not mention the "famous" brand but i can tell you it's all light green : close it, then restart your lol launcher ... let me know if this helped

There are several ways to fix this:

  • Restarting your computer will make it work once. (you've figured this one out yourself)
  • Heading over to C:\Riot Games\League of Legends\RADS\Projects\ and delete the "lol_air_client" folder. Run the patcher, let it patch (it'll fix the game) and it will, again, work once. Closing the client will cause the issue again.
  • Setting Internet Explorer to default settings will also temporarily fix this but it requires a restart to complete which applies the first fix so it's redundant.

Permanent work around:

  • Run the patcher, click Launch. When nothing happens, go to C:\Riot Games\League of Legends\RADS\Projects\lol_air_client\releases\0.0.1.119\deploy\ and double click on the LolClient.exe. If this is a recurring issue, I recommend creating a shortcut to this file. Note: Running this file will only work if you ran the patcher first, running it without the patcher will simply crash it. That's it! You're in!

For anyone reading this for other versions of the game (in the future) the number 0.0.1.119 is only for the 4.20 patch, open the latest version whenever possible.

Riot should seriously consider spending a lot of time and money to fix this issue. Nearly everyone I know that plays League has this issue on a regular basis. What good is a game launcher that doesn't launch the game?

I have had this problem for a while and tried many things to fix it. After finding this thread and following Happy Poro's advice, which I was very optimistic about, I have not solved this issue. If I restart my computer and enter the game right away it will launch- but then inevitably the issue is back after a little while. At this point I implore Riot to come up with some official answers here because as "pwnvader360" has said there are many people- even just the ones I personally know- with this same issue.

The Maestro Error pops up when you dont run the Patcher first. Run the game normally, click "Play" first. If you dont do this step, Maestro doesn't start up and the client crashes with that error.

It could also be an anti-virus issue. My Norton blocks League by default. I have to manually let it through the firewall. But every time a new patch comes in that modifies the executable, Norton blocks it again. It's very frustrating.

So this is what I have to do: http://gyazo.com/5ab23b1b6db9b63b36a94a47b4fbd1e2
