League Won't open after clicking "Launch". May have found a partial solution/clue.

I have been having this problem since 4.19. After a new patch would come out I'd find myself not being able to launch the league client. I'd then spend a few hours trying all sorts of stuff and then out of the blue one of the 'fixes' would work until I close my client to which I'd find myself trying all the different fixes again for another few hours. However it came to my attention today when I opened up my task manager in windows 7 to force shutdown of the LolClient.exe process. I right clicked it and accidentally clicked "Open file location". It brought me to C: > Riot Games > League of Legends > RADS > projects > lol_air_client > releases > 0.0.1.118 > deploy. When I ran "LolClient.exe" it brought me directly to the login screen before giving me a brief "Maestro error" before closing. I ran the game client from my desktop icon and clicked "launch". I then checked task manager to see if LolClient.exe was running in the task manager. I then went back to the league directory and double clicked LolClient.exe and it brought me to the login screen without the Maestro error and I'm able to play the game. I have to do it this way every single time I want to play league. To sum it all up I start the client launcher and click "Launch". When the client won't pop up, I open up the directory I mentions before and double click LolClient.exe and it brings me to the login screen from which I can login and proceed to play the game normally. Riot I hope this helps you find a solution to help anyone else that may be having this problem as well. No matter what I've tried i haven't got it to stop doing this. I repaired installed, tried adobe air, I tried deleting certain folders and files under RADS, tried a fresh install of the game, all to no avail.

EDIT: I also failed to mention that the first "Lolclient.exe" that pops up in task manager stays stuck at a certain memory usage level. For example the memory LolClient.exe is using will be something like 4,140K and stay stuck at that number. But when I run the LolClient.exe file from the league directory, it will create another process called LolClient.exe but it's memory usage will be more dynamic and fluctuate.

There is a much easier way to fix this problem! So what you want to do is go to Local Disc< Riot games < League of Legends < RADS < Projects< lol_air_client < releases < 0.0.1.1.136 (If you dont have that one it could be others doesn't matter.) < Delete releasemanifest & S_OK. (Close tab.) Open League of Legends, then wait for it to update. (It took me about 5 minutes) When its done launch it and your finally able to play! Hope this helped. :)

There is an easy fix! :D so first thing you will have to do is right click the launcher then, click on Troubleshoot compatibility after, click on recommended setting. it will change the setting for the program. Click Test the program. It probably wont work so click next and click no it didnt fix the problems something like that... then select The program wont display correctly.. and then test the program it will work fine :D

IDK how the league forms system works since i dont post much but if i fix something I find and post things... so Up vote this it will help out many people :D

I recently did a system restore, to a point about a week ago. It (5.2) was working fine, now the client is closing without even running in task manager.

Having the same issue as above. Thank you for documenting it.

Mitch3ll12/3/2014, 4:31:46 PM5 votes

STILL having this issue. RIOT PLZ.

The only way I can seem to get it to work is by using lol.launcher.admin.exe instead of lol.launcher.exe but that's only a work around. It only started happening this patch (4.20) and I have been playing since Season 1.

Can confirm - right clicking the LolClient process in the task manager, and going to file location, and running the LolClient from here will bring up login screen. Thanks for the info.

I'd like to bump this, as I am having the exact same issue. Is anything being done?

Byrnes11/21/2014, 3:52:27 AM4 votes

Mine will launch after I close iTunesHelper. Not sure if this helps, but this has worked 90% of the time for me.

Biggie Mediums2/8/2015, 6:22:59 PM3 votes

I'm having this same issue. I have to keep launching the launcher and hitting launch, ending the process(es) and re-opening the launcher until it decides to work.

Zaxamaphone1/28/2015, 10:24:19 PM2 votes

I have the same issue. I open the launcher, click launch and it goes away. Sometimes it will open the log in screen and other times it will not. The process is always running, even if I am unable to get to the log in screen.

I am also having this issue. I have to kill all of the League stuff via the task manager and then attempt to relaunch and nothing I have attempted has fixed it, including this post.

Created a shortcut to desktop seemed to work for me.. even though there was already a launcher on the desktop I created another one and now league works after clicking launch.

Open every file under LOL RADS Projects and delete every file under release then launch it worked for me

theDENNISsystem12/13/2014, 12:06:10 PM2 votes

Same here. I can get it to launch one time after I reboot, then I have to reboot again if I close League.

BUMP

I have been getting this problem since the latest patch, I've tried every possible "solution/fix" and i am still getting this, all the troubleshooting, deleting air client/launcher/patcher files, complete reinstall, you name it. Even getting the patcher to patch from the base client is hard enough. Once i hear the dinging sound and click launch, nothing fucking happens. I have a 60hz monitor oc'd to 120hz, have tried different refresh rates/resolutions, reinstalled adobe air. Sometimes i have to review the eula/toa everytime after clicking launch. I've run multiple spyware/antivirus tests (using bitdefender/malwarebytes), i also believe that bitdefender has included the lol processes under the exclusions, as it has always worked fine with LoL.

I have read that people have received issues after a system restore, I had done one recently but i'm pretty sure the issue persisted before the system restore. I really need some possible solutions besides the usual copy paste troubleshooters, and literally anything else posted on these forums.

OMFG...after all these time... I've been looking up how to solve these problems and it never worked! But I finally found a way to make it work... What you want to do is turn off ANTI-VIRUS AND FIREWALL, those are the main reasons why it's preventing LoL to go into the login screen within these new LoL patch/updates... It's the reason why whenever there's a new patch/update it doesn't update because anti-virus is blocking it from doing so. So after you've turned off anti-virus and firewall, delete the lol_air_client folder which can be found at: C: > Riot Games > League of Legends > RADS > projects > lol_air_client. Or you can reinstall it however you like. After you've done that, run LoL launcher then let it patch. After it has finish patching, and this is another important step. Re launch your LoL launcher then DISCONNECT YOUR INTERNET and simply press PLAY. It'll turn grey and you have to be very patient. It'll come up with those terms and conditions. Wait for it to pop up and press accept twice, wait for a little longer then you should be in! After you get into login screen, make sure you TURN ON YOUR INTERNET again and login in. DONE! I HOPE THIS HELPS!

My league client opens but when i click the launch the log on screen never appears. I also just updated to 6.1 and i need assistance

Joseale231011/19/2016, 6:58:55 PM1 votes

(Patch 6.22) What worked for me was to remove League of Legends from the firewall permissions and then add the new LeagueClient in the C/Riot Games/League of Legends/LeagueClient. I also added the lol.launcher.admin to the firewall permissions. Don't launch LoL from your old shortcut, create a new one from the lol.launcher. Now it works after the Launch!

same problem, started today and wont open past the initial launch screen no matter what

Orneryman11/28/2016, 1:29:29 AM1 votes

If you're like me and had this issue when installing fresh on a PC (I would install the game, open the patcher, press launch and it wouldn't patch the game and open up.) I changed my refresh rate from 144hz to 60hz and it instantly started patching. Found this fix thanks to the Riot Support page.

EASY FIX! Go Leauge of Legends-> RADS->projects->air_client->releases->0.0.1.232(1,8 Gb) then delete it. Open the lol launcher then close when it will be starting to scan the files. Take back the 0.0.1.232 file from recyclone bin. After that you can open the launcher and it will be work fine.

I tried deleting LolClient.exe because it told me it was corrupted and the file could not be read. Stuff seems to be working fine for me now.
