Hey guys, there are currently two ways to go back to the legacy client if you're having issues with the updated client. This should also fix the issue where your updated client is failing to launch and all you see is an empty black/blue box.
1- On the login screen of the updated client, click on the "Launch Legacy Client". - image
2- If you're running into issues launching the updated client and thus cannot click on the "Launch Legacy Client". Follow these steps:
- Go to your League of Legends install folder. Default is (C:\Riot Games\League of Legends) go to \RADS\system
- Locate the user.cfg file and open with notepad
- Change leagueClientOptIn = yes to leagueClientOptIn = no
- Save and go to your League install directory and run lol.launcher.exe
Please help us investigate this issue by submitting your logs.
