Vanguard not installing especially after uninstalling

Hey there, quite recently I have been receiving this dependency error issue. After uninstalling vanguard, it seemed to be continuing the same error and I have tried multiple methods such as running the program in administrator, downloading vanguard on another device and copying it over to my program files, deleting all related riot client and valorant files, reinstalling valorant multiple times, disable windows security anti-virus and firewall temporarily to try and install the riot vanguard service.

The only things I want to avoid doing is reinstalling Windows and formatting any drives as I hold many important files and accounts on the Windows 10 computer and plus I don't fully own the computer so don't really have the full permission to do so.

Better to ask here if there is any other solutions before contacting player support team.

hey, launch a command prompt as admin and run these commands :

sc delete vgc
sc delete vgk

sc delete vgc
sc delete vgk

once you've ran these commands, restart your pc, open the file explorer and go to C:\Program FilesC:\Program Files and delete the folder Riot VanguardRiot Vanguard

then, download vanguard setup file and run it : https://riot-client.secure.dyn.riotcdn.net/channels/public/rccontent/vanguard/1.16.16.9/setup.exe

finally, look in your C:\Program FilesC:\Program Files folder if there is a Riot Vanguard folder, if there is try lauching valorant

error might also come from a software installed on your pc

dont run any setup

AbhimสŇyu•1/20/25, 9:12 AM

just open the riot client again after uninstall it should work

I'll have to check this out once I get home.

ajcox_OP•1/20/25, 9:53 AM

I doubt this is the case, some people including me have uninstalled vanguard and trying to open riot client to install vanguard once again will then provide the dependency error and therefore no files of vanguard will be installed at all

I'll still give it a try but I'll try this method first later.

I'll let you know when I get home in a couple of hours.

ajcox_OP•1/20/25, 2:41 PM

Trying to perform sc delete vgc or vgk on cmd with administration permissions does not work at all unfortunately and trying to find Riot Vanguard folder does not exist whatsoever. The vgc service doesn't exist anywhere and despite all of this, it's still producing the dependency error which therefore isn't allowing me to download the file there. When trying to run the setup.exe with non-admin perms or with admin permissions, nothing happens whatsoever so unfortunately nothing worked so far.

AAbhimสŇyu run these cmd in admin command prompt

Any common softwares that may interfere with valorant or the installation process at least would you know?

Download auto runs from the system internal suite

When you have it open press file, and then run as administrator
Then uncheck anything that is red or yellow
Except Vanguard and anything that fails to be unchecked
Restart your computer and then try the game again

jpplol•1/20/25, 5:09 PM

yes nothing should happen, you are supposed to have the Riot Vanguard file in your C:\Program Files directory (you can follow jidat's instructions too, he knows more than me)

ajcox_OP•1/20/25, 6:34 PM

I understand I'm supposed to have the Riot Vanguard file but it is totally missing and the dependency error wouldn't allow me to reinstall all the files again no matter what and the setup.exe didn't seem to function either.

open event viewer (search in windows search bar), open the Windows LogsWindows Logs tab then select the SystemSystem option

launch the setup.exe file and look for errors

jpplol•1/20/25, 6:40 PM

you can also search in your %temp% folder (search in windows search bar) for any folders with names that start by 7z7z, open them and look for this (if any folders found)

ajcox_OP•1/20/25, 7:07 PM

Nothing found from %temp% files just yet and still no logs generated even when trying setup.exe multiple times. I'm still going to see if I can find any logs in a bit but just a question, even if I'm using a Windows 10 operating system and not Windows 11, would it be necessary to enable secure boot and would that partially be why I might be having problems or not really?

jpplol•1/20/25, 7:08 PM

don't think so

jpplol•1/20/25, 7:08 PM

you can also look into the application option instead of the system option

ajcox_OP•1/20/25, 7:12 PM

Doesn't seem like I'm getting logs from either system or application option unfortunately. Not a clue what's causing riot not wanting to install vanguard or even run the setup whatsoever.

jpplol•1/20/25, 9:36 PM

do you have any other event that showed up (recent ones can be any)

jpplol•1/20/25, 9:36 PM

might be because the event viewer service is disabled

ajcox_OP•1/20/25, 11:45 PM

I'll check this tomorrow and let you know, going to get some sleep for the next day.

Jjpplol do you have any other event that showed up (recent ones can be any)

ajcox_OP•1/21/25, 4:16 PM

Yeah, there are definitely recent ones for sure so doesn't seem to be disabled and I doubt they're related to Valorant whatsoever even after looking through the specific detail of each log.

jpplol•1/21/25, 4:31 PM

im pretty sure that any program that interferes with the vanguard setup would be reported as an error/warning in the event viewer, so any information event is useless

Jidat•1/21/25, 4:32 PM

Press win+r
Type sigverif
Press enter
Run the utility
Show result when done

JJidat Press win+r Type sigverif Press enter Run the utility Show result when done

ajcox_OP•1/21/25, 5:40 PM

That's the result.

ajcox_OP•1/21/25, 5:43 PM

Rare occasions this error occurs especially if I try running VALORANT.exe from 'C:\Riot Games\VALORANT'

ajcox_OP•1/21/25, 5:45 PM

and most commonly I do find this in the system event viewer error logs but I don't know if it's related to the vanguard issue right now. I wasn't sure if it was even necessary for Windows 10.

ajcox_OP•1/21/25, 6:15 PM

Holy crap I fixed the dependency error, what it took was for me to go into BIOS mode, switch from CSM mode to UEFI mode and it installed Vanguard and the dependency error isn't there anymore.

ajcox_OP•1/21/25, 6:16 PM

However I'm receiving this error again so got to see what is that about but now instead of this looping, it managed to create a crash log instead of it going back to the same error.
