If this is your first time playing you will need to reboot your computer to continue. If you see this message frequently you may need to update your drivers." We look at some of the possible causes as well as solutions to Valorant error code 128.

How To Fix Valorant Error Code 128

Update drivers

You can start off by doing what is suggested in the error message, which is restart your system and update your drivers. You can update your drivers manually through the Device Manager located in the Control Panel. You may need to download the latest version of your drivers from your graphic card manufacturer’s website.

If this doesn’t work, you can try downloading and installing driver updates from the ‘Optional Updates’ section in your Windows Update tab.

Make sure Valorant Vanguard service is running

Open command prompt in admin mode by going to run through Windows + R and typing cmd. In the CMD prompt window, run the commands below:

sc query vgc

sc query vgk

If it says the service is not available, you will need to uninstall VALORANT and Riot Vanguard. After this do a fresh download and reinstall the latest version of both the game and Riot Vanguard programs. However, if you see vgc service is available, start Vanguard manually by running the following command:

net start vgc

After doing this, check if Valorant Vanguard error 128 is resolved. If it still does not resolve the error, repair VALORANT through the Riot Client.

Open the Riot client and click on the silhouette icon on the top right corner of the screen. Navigate to ‘Settings’ in the drop down menu and go to the Valorant tab on the left.

Here click the ‘Repair’ button to initiate a game repair.

Unfortunately, If none of the above methods helped you at all you will have to submit a ticket by contacting Valorant support through this.
