How to fix League of legends vanguard errors even if your bios supports only Tpm 1.2

If you have tried all this solutions and it didn't work, I really recommend you guys to reinstall your windows and start fresh.

Note!: If you are using win11 with TPM 1.2 You cant launch the game !, install win10 and it will work with you with TPM 1.2

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

Note!: If you found only one file, Create one !

- Right click -New-DWORD (32bit) value, name it (DevOverrideEnable) and make it 0

I've vanguard 9001 error. When i check my tpm by command "tpm.msc" it says that it is not supported, so I think I don't even have tpm 1.2... any solutions? Lol on pc does works normally, I've even W11 installed (IDK how considering that I've no tpm, I send my pc to a store which installed W11 for me from W7), My processor is 4th generation too (Intel I5-4440 3.1 ghz), my motherboard is a MSI H97 PC Mate, GPU Nvidia gforce GTX 1650 ventus.

I have 1.2 and secure boot enabled on winsows 10, I start up league and now I get a vanguard error after 10/15 seconds, any ideas?

[reconmaster]

This does not work on my system. I have an hp z420 with more than required requirements, TPM 1.2.
I wasted so much of my time and resources in downloading this game with my slow, metered internet. and after downloading 20+ gb, it refuses to launch just because of this stupid anticheat. It should have told me that my pc is not supported before downloading all that crap.

[leonschneider]

i have tom 2.0 secure boot ist enabled and it’s on uefi but vanguard won’t download

[eyad]

In the registry editor method i don't have the file you changed

[lordmaximus]

I have a 2021 pc and for some reason my pc doesn't even have a tpm???

[affan]

my pc has tpm 1.2, i can start the client and the client starts fine in start but after 10 secs, vanguard error appears that i need tpm 2.0 to run and game closes. :(
tried that registry editor thing but in that directory, there is n o seconf file, only the first one. I guess without tpm 2.0, i cant play

[andrejsbluks]

What if I do not have that DevOverride ?

[madwolf]

dude u have win10 there should be no problems as riot eng. said ! the real problem if u have win11 and your pc only support tpm 1.2 ! i already have an open ticket with riot about this problem

[CravoneYT]

As with all the other useless guides no-one explains how to turn on secure boot. I am clueless with it, was hoping this guide might actually not completely skip over how to do that.

[LucasInTheAyer]

Riot is worthless for having this update

[yousseflamnouar]

Thanks for this solution.i will try it and tell you what's up
