This is a unique method when some users report that they can start the game using a VPN.
When the process disappears, try to open Steam again using the shortcut. Once there, find and select the app League of Legends. Rightclick on the taskbar and in the menu that opens select Task Manager. You can try to kill the process manually to restart LOL: If you can’t even see the League of Legends launcher, the LOL process may be stuck in a faulty state where you can’t even open it. Then the app will start downloading the game patch again, and hopefully, the error will be fixed as well. Finally, close the File Explorer and open LOL. Then open the deploy folder and remove these files: lib (folder).
On this folder remove these two files: releasemanifest and S_OK. Now there navigate through the following path: rads > projects > lol_air_client > releases >. In the box copy the path C:/Riot Games/League of Legends and press Enter. Open the Run window using the keyboard shortcut Win + R. This method is highly recommended in all the forums and means that you will remove the game patch files, so then LOL will download these files again and fix the problem. Click on Apply to save the changes and try to open LOL. Now on the dropdown, try each one of these options: Windows XP (Service pack 3). Then, check the box Run this program in compatibility mode for under the section Compatibility mode. A new window will open and there navigate to the Compatibility tab. Now, in the menu, click on the option Properties. Go to your desktop and there right-click on the League of Legends shortcut. If you haven’t able to open League of Legends before and always see the error, you may need to enable the compatibility mode on the shortcut properties. Now every time you open LOL from that shortcut, you will be asked for admin rights directly. Finally, there check the box Run this program as an administrator. The Shortcut properties will open and there navigate to the Compatibility tab. Go back to your desktop and right-click on the LOL shortcut.
If the game works when you enable the admin rights, you can enable this option permanently following these steps:
Now, it most cases the game will open without problems. In the menu that opens, click on the option Run as administrator. Go to your desktop and right-click on the League of Legends shortcut. First, you need to check if the game works as an administrator: You may not try this before, but sometimes LOL requires individual permissions to be able to run all the components correctly. That’s why on this post, I want to help you if you have the same error on your PC. But, the following happened… An error after the update that the client won’t let me open! After searching on forums and asking for help, I was able to fix this error. Some days ago, I woke up and wanted to play some League of Legends before going to college.
