How to Fix Valorant Vanguard Not Initialized Error Code 128

As would be expected, the "Vanguard Not Initialized" error is related to problems with Valorant's anti-cheat system. It happens as a result of either improper installation of the anti-cheat software or Windows and other applications conflicting with Vanguard's "VGC" service. In addition, driver conflicts or particular system settings may serve as the causes of this issue.

The following article describes various ways to resolve this error.

1. Disable Test Mode for Windows

When you run Windows in Test Mode, untrusted drivers and applications may run, which might mess around with Vanguard's security settings. You can perhaps sort out startup issues you may be experiencing after disabling Test Mode-also make sure that only certified drivers and applications run, just as should be for Vanguard.

Press the Windows Key + X to get the Command Prompt (Admin) or PowerShell (Admin).

Run the following commands separately in order to exit from the Windows Testing mode: bcdedit -set Turn off testing

After opening Valorant, click "Reboot Computer."

You should now be able to play Valorant after your computer has rebooted.

2.Enable "Automatic" for the Services.

For all Vanguard services, such as "VGC," make sure they are set to "Automatic" when your computer is booted. In this way, failure to start the service late or not at all will reduce the occurrence of failures within Valorant's anti-cheat system.

Press X and then the Windows Key. Select the Command Prompt (Admin).

Key in the following commands one after the other: Create vgc to be on demand sc

Configure vgk to automatically start in the system configuration.

Open Valorant now and click on the menu that says, "Reboot Computer."

After your computer has restarted, please check if the Vanguard service and driver is as follows:

Press the Windows Key and X then go to the Command Prompt (Admin).

Type in these commands:vgc query sc

sc find vgk

In case you receive an error message from the system stating that a service is unavailable, remove Valorant and Vanguard, and reinstall them. Then, manually start Vanguard using the following command-if the service name vgc is shown: running vgc

See if the issue still persists.

3. Repair VALORANT

Repairing Valorant ensures that all the important game files, including those necessary for Vanguard, are checked and fixed. It also solves the problems brought about by partial or damaged installations and completes everything.

4. Driver Signatures

Outdated or incompatible drivers can interfere with your system processes through Vanguard. Drivers must be scanned for updates and verified to be signed and operational to keep Vanguard running more efficiently and with fewer errors.

Open the Run dialog by pressing the Windows Key + R.

To access it as an administrator, open Command Prompt by typing cmd in the search bar and pressing Ctrl + Shift + Enter.

Type the following command and hit enter: set {current} bcdedit.exe turn on nx opt-in DEP
