Can’t jump into the Rift for another win streak? If you’ve encountered the frustrating “We Couldn’t Install A Required Dependency” League of Legends (LoL) error, you’ll know that it can be a serious mood killer. This can prevent you from running not just LoL but other Riot games like VALORANT too. You don’t have to worry anymore, though. There’s a few ways to fix it yourself, and we’ll walk you through several proven methods.
Understanding the Dependency Error
First, let’s understand where the problem comes from to know the potential fixes. The error typically stems from issues with Riot Vanguard, the anti-cheat system integrated into the game. This will show up as a message that says “We couldn’t install a required dependency” when you try to run League of Legends.
Here, the problem is with Vanguard’s installation or configuration. It then blocks you from launching the game, much to the frustration first of VALORANT players, and later on those of LoL. Fortunately, most fixes can be completed in just a few minutes.
Quick Troubleshooting Steps
Since it’s a system and installation problem, let’s start by addressing those first.
Restart Your System
The age-old simple approach of restarting the system may just work wonders.This basic step resolves many dependency errors by refreshing system processes and temporary files.
- Close the League of Legends client completely
- Restart your computer
