Why Isn’t League of Legends Installing?

Administrative Access

The first thing to note is why you can’t install League of Legends on your system. If you do not have administrative access to your computer or anything that is interfering with your network connection then the game might not install.

Outdated Version of Windows

Another possibility of the game not installing is that you might have an outdated version of Windows. In this case, you will need to update the version of your Windows and then attempt to install the game. The game supports Windows 7 and onwards.

Firewall Settings

Another big issue that might be preventing the installation of the game is your firewall settings. Improper DNS settings might create issues with your internet connection which results in LoL not starting. It is possible that certain program files might have been damaged during the entire installation process.

No Space Available

A major reason that you might be overlooking this entire situation is the space on your system. If you don’t have sufficient space on your PC, the game might stop installing midway. That is a huge letdown considering several files have already been installed and once installation stops you have to start it all over again.


The Antivirus in your system might be the application that is blocking the installation of LoL. If your Antivirus is active while installing the game then you can disable it for the time being. This is to make sure that the game installs on your system without any issues or bugs.

Fixing League of Legends Installation Problem

Here are some ways using which you can fix the League of Legends installation problem.

Freeing Up Space

You can free up space on your PC and carry out a complete installation from scratch by going through your drive via Riot Games > League of Legends > Logs > LeagueClient Logs and this will pull up all your recent logs. You can then delete them to free up space. The other location is under your AppData folder.

Another way to free up space is by removing the folder “/Riot Client/” from “C:” (or the disk you installed it on), then go to “C: Riot Games” and delete the folder “/Riot Client/” from “C: Riot Games”. This software is fairly portable, which is why it isn’t mentioned in Windows’ “Programs” list. This makes it completely okay to remove the folder and it will leave behind no remaining files of any kind.

Restart Your Computer

Despite not being created specifically to address League of Legends not starting issues, the option to restart your computer does work.

The temporary data is removed when you restart your computer. It’s possible that some of this temporary data was damaged and affected LoL. It’s preferable to erase this immediately away because it happens frequently. All the LoL applications that failed to launch are likewise closed by restarting your computer, allowing you to start over.

Launch Game From Installation Folder

Additionally, it’s not unusual for the shortcut symbol to be the problem. Unfortunately, it can also quickly become corrupted and stop functioning properly. As a result, when you click on it, nothing happens.

The League of Legends shortcut on your desktop can be removed or moved. After that, go to your installation folder and open the “LeagueClient” program to start the game. You can also attempt the next solution if this doesn’t work.

Close All Running Applications

If you’ve already used the LoL icon a lot or if your computer has been operating for a while, there’s a good probability that numerous programs are still running in the background. And closing them might enable League of Legends to install. This is particularly true if you’ve just used Steam or Razer Synapse, which frequently triggers the problem.

Here are the steps to follow in this case:

  • Open Task Manager by clicking on your taskbar
  • Search for any LoL, Steam, or Razer Synapse application and close it
  • Go to the “Startup” tab and disable all the applications which aren’t needed while installation
  • Then close the Task Manager and launch the game via “LeagueClient”
  • Run the game as an Administrator

Running Game as Administrator

On some systems, there is a common problem where users can’t run the game when they don’t have admin permissions. To run the game you will need to run it as an administrator. If this problem is showing up for you then it will end up solving the problem.

All you have to do is choose “Run as Administrator” from the context menu when you right-click the “LeagueClient” or “LoL” icon. When asked if you want the app to make modifications, you can then select “Yes.” Hopefully, the game will begin installing.

Updating Game Client

Updating the game client is also a good way to make sure you get to run the game. The League of Legends game client is prone to several errors. Sometimes it’s the .dll files that get corrupted for no reason. Due to this, LoL doesn’t run the installer. Updating the game client makes the installer run smoothly. Follow these steps to update the game client:

  • Go inside “Projects” and delete the “lol_launcher” and “lol_patcher” folders.
  • Go into the League of Legends installation folder and only delete the “aps_ms_win…dll” files.
  • Launch the client by clicking on “LeagueClient.”
  • Let the update process finish.

Replace Projects Folder

In the “Projects” folder are hidden files that are required for the game to launch. Repairing this folder can solve the issue of League of Legends not installing. Here is how you can troubleshoot this problem:

  • Open the “RADS” folder inside the game’s installation destination.
  • Cut the “Projects” folder and paste it onto your desktop.
  • Launch the game via “LeagueClient” and wait for the update to start.
  • While the game is updating, move the “Projects” file back to its original place.
  • Choose to keep the first (the one you replace).
  • The download should end immediately after which you can run the game’s installer.
