The "We Couldn't Install a Required Dependency" error can appear when downloading VALORANT or League of Legends for the first time and while installing updates. The message box associated with this error mentions a quick fix, but you may need to try other methods for a permanent solution.

The dependency error has been around for a while now since it first showed up alongside the Riot Games client in 2021. Over the years, players who can't install games or updates because of dependencies shared working solutions on platforms like Reddit. Nowadays, it often takes a few minutes to fix the "We Couldn't Install a Required Dependency" error in VALORANT and LoL, and here's how you can do that.

How do you fix the "We Couldn't Install a Required Dependency" error in VALORANT?

The easiest fix for the "We Couldn't Install a Required Dependency" error in VALORANT is deleting the Vanguard anti-cheat software. This fix works because the required dependency mentioned in the error looks tied to Vanguard files.

When you uninstall Vanguard, you'll force the Riot Games client to install its most updated version.

1. Uninstall Vanguard.
2. Restart your computer.
3. Launch the Riot Games Client.
4. Let it install all available updates.

The Riot Games client is unlikely to run into any troubles after the Vanguard installation, and the anti-cheat software will be back on your system after the client finishes all download processes. Over time, the error could come back. When that happens, you can repeat the steps above.

Vanguard is one of the better in-house anti-cheat software out there, but sometimes it can confuse players. For example, Vanguard requires players to enable secure boot for VALORANT, which requires familiarity with BIOS settings.

How do you fix the "We Couldn't Install a Required Dependency" error in League of Legends?

To fix the "Required Dependency" error in LoL, you should delete Riot's Vanguard anti-cheat from your system. Similarly to VALORANT, having Vanguard on your system is necessary to play League of Legends and VALORANT. Considering the "Required Dependency" error is tied to Vanguard, you'll need to remove it to fix the "Required Dependency" error.

1. Navigate to your control panel.
2. Look for "Uninstall a program."
3. Find Riot Vanguard and uninstall it.
4. Restart your system and launch the League of Legends or Riot Games client again.

Alternatively, you can try changing your DNS and completely reinstalling the game. Overall, this is an anomaly that concerns Vanguard's files or processes. Though there are a few temporary fixes, it could take Riot Games to release a patch for a permanent fix.
