Launching League of Legends on Windows 10 can sometimes be more difficult than fighting hordes of vicious enemies.

Many players report they often can’t launch the game due to various error messages or simply because nothing happens when they hit the play button.

If you’re experiencing League of Legends start issues, you’ve come to the right place. In this article, we’re going to list a few workarounds that will help fix these issues and launch the game.

First, let’s see how one gamer describes this issue:

I updated to the new client yesterday and everything was great. I logged out and today the launcher starts but after I hit “Launch” the launcher disappears but no client. Task Manager shows 2 instances of “League Client (32 bit)” running under ‘Background processes’ but I can’t bring it up anywhere. Trying to launch the launcher again gives me the ‘game already running’ pup-up so that’s no help.

How to fix League of Legends launch issues

1. Reinstall your graphics card drivers

According to users, sometimes League of Legends won’t start due to issues with your graphics card.

Your graphics card is crucial for gaming sessions, and if there’s a problem with your graphics card drivers, you might not be able to start League of Legends at all.

To fix this problem, it’s advised to remove your graphics card drivers and use the default drivers instead.

There are several ways to do that, but if you want to completely uninstall your drivers, we suggest you use Display Driver Uninstaller to remove them.

Once your drivers are removed, restart your PC and Windows 10 should install the default drivers instead. Once you install the default drivers, check if the problem still persists.

In addition to using the default driver, some users are recommending to install an older version of the graphics driver, so you can try that as well.

Try the next solution if this didn’t fix the chop.

Update drivers automatically 

Downloading drivers manually is a process that carries the risk of getting the wrong driver installed, which may lead to serious malfunctions.

Not only, is there the risk of downloading the wrong drivers, but you can also end up installing a version that isn’t even the latest eitehr.

Big-time gaming can be done without crashes, lags or freezes by keeping all drivers up to date and error-free. Manual checks are hard to perform, that’s why we recommend using an automate assistant that will scan for fresh driver versions daily. Here is how to use it:

  1. Download and install DriverFix.
  2. Launch the software.
  3. Wait for the newly installed app to detect all your PC’s faulty drivers.
  4. You will be presented with a list of all the drivers that have issues, and you can choose the ones that you want to fix.
  5. Wait for the driver download and fixing process to complete.
  6. Restart your PC for the changes to take effect.
