The Reason behind Valorant Error Code 66

The Valorant Error Code 66 is a bit hard to understand, but knowing the reason behind it is key to know what solution might work best to fix it on your Windows PC. On the official Riot Games support site banner it is stated that the reason behind the Valorant Error Code 66 is due to “ContentIndexInitFailure”. The Valorant game runs on background processes, and what this essentially means is during the startup process, something went wrong with processing the game content properly.

The first reason this might happen is if a bad start of the Riot Client was performed. The Riot Client has been known to cause a lot of error codes in the game, so it’s no surprise it can cause the Valorant Error Code 66.

Another reason for the appearance of Valorant Error Code 66 might be with the Riot Vanguard, more specifically with the VGC service that it runs in the background. The issue with this anti-cheat system is that it is one of the best anti-cheat systems out there, but it runs notoriously behind the scenes. So if the Riot Vanguard recognizes the game content as bad, it can cause the Valorant Error Code 66 to appear, especially with a bad VGC service start.

Knowing why you are getting the Valorant Error Code 66 is a must, so next up you will know why every solution might fix your issue. So let’s not waste any more time and jump into the solutions!

How to Fix Valorant Error Code 66

Restart Riot Client

The first solution you can try out to fix this issue, that even Riot Games themselves recommend you try out first, is to restart the Riot Client. The Riot Client causes a lot of error codes, especially for gamers with a bad Windows PC.

To do this easy fix and restart the Riot Client, you will first open up Task Manager by pressing Ctrl+Shift+Esc. Select the Processes Tab above and locate the Riot Client. Once you locate the Riot Client, select it and click on End task to close off the Riot Client process.

Change Startup Type of VGC Service

The VGC service that the Riot Vanguard runs in the background can cause the Valorant Error Code 66. In this situation, you should change the startup type of the VGC service. Much like with the session service, if the VGC service does not start up as it should, Error Code 66 might appear.

To do this, firstly make sure you have closed off Riot Vanguard and Riot Client from the Task Manager (Ctrl+Shift+Esc). You can also check the System Tray (arrow pointing upwards below on Windows Taskbar), and if you see the Riot Client or Riot Vanguard, right-click them and close them off. Then click the Windows key + R (Win+R) on your keyboard, which should open the Run window. Type in “services.msc”, and once the Services window opens up, search for the “vgc” service. Once you locate it, right-click it and select Properties. In this tab, change the Startup Type from the settings to Automatic, click on Start and select OK.
