[2020] Vanguard Anti-Cheat not enabling.

Original Post — Direct link

I was able to play Valorant the past two days until my graphics card crashed mid game. After this, Valorant could no longer be launched because "Anti-Cheat has not finished installing".

I've tried everything on Reddit alongside disabling my keyboard and Razer mouse software. Disabling firewall + anti-virus. Everything set to run as admin. Full uninstall of everything Riot Games related (completely cleaned out with Everything).

When trying to start VGC from Services, I get this error:

Windows could not start the vgc service on Local Computer.
Error 1: Incorrect function.

I have updated everything for Windows and tried:

bcdedit -set TESTSIGNING OFF
bcdedit -set NOINTEGRITYCHECKS OFF

^ before it allowed me to use these commands, I had to turn my ASUS Secure Boot off.

No matter what, my VGC will not turn on and I always get Error 1: Incorrect function.

Nothing has worked and Valorant always gets stuck at "System Reboot Required".

Please Riot Games help me..

can you look into this please? Plenty of people suddenly started having issues starting Vanguard.

When checking in services.msc we get this error: https://imgur.com/faCGU3M

hey friend, I've raised with the team, but I would recommend anyone experiencing issues please open a ticket with Player support, which will get your issue resolved faster than pinging individual rioters!

Check to see if you have any unsigned drivers running using the sigverif command. They'll show up in the resulting list next to a file icon containing a gear.

For me, it was an nvidia driver. Updating them fixed the issue for me.

this is good advice!

This problem can sometimes occur if your device drivers are out of date, not signed properly, have been modified or are otherwise kind of busted.

This page has a few methods on how to detect drivers like this so you can update or remove them: https://www.drivethelife.com/windows-10/check-unsigned-drivers-on-windows-10.html

/u/zigzagdance recommends "sigverif" which comes with Windows, that or "dxdiag" are my preferred methods.

There are other reasons that this error can occur but this is worth a shot if you run into the problem!

Hey! @RiotArkem I rand sigverif and it says nvcpl.dll is unsigned. nvcpl.dll is the library for Nvidia control panel and I have clean installed the latest Nvidia drivers.

Only unverified drivers (.sys files) should cause a problem so nvcpl.dll appearing on the list shouldn't be an issue. If you're still having a problem I recommend a support ticket.

what do i do with a unsigned files if i scan with sigverif?

For any unsigned driver files (.sys files) you should either remove them or try to update them to the latest version.

Sigverif shows 3 files associated with the Asus Xonar u5's (a sound card) driver. Turning off the driver allows the game to boot without issues. Please unflag these files... asusu5.sys bazivirtualcdbus.sys taphss6.sys

Can you link me to somewhere I can get those actual files?

Sure! Windows 7 64-bit latest version: https://www.asus.com/Sound-Cards/Xonar_U5/HelpDesk_Download/

Installing the driver should give you the files. If it does not, please tell me and i'll upload them.

Thank you for taking the time to try to fix this. Currently the only way i run the game is closing the driver, opening game then opening driver again. :p

Ok, I'm looking into it. These drivers look pretty old but maybe we can find a way to whitelist them.
