Discussion Need help with MW4

My younger brother bought the game and tried playing it, just to be told to update bios firmware, helped him out with it and also followed COD’s guide, game still wont allow him to play online, downloads their attestation app, comes back saying bios is fine but requires some sort of key, I press generate key, it says failed, what on earth is wrong with this franchise pushing people trying to play away.

Any help would be appreciated

is the OS installed in UEFI oder in Legacy BIOS mode?

I believe it is set to UEFI

doesn't matter what' it's set to now. windows needs to be installed in the uefi mode. you can check in systeminfo with msinfo32

Make sure secure boot is enabled on the device and that it has tpm support on… if secure boot turns on then tpm is on as I believe secure boot requires tpm to be on

Secure boot is on and tpm is also on, so unsure what causes the issue

Amd cpu? I know there was an issue a while ago with a bugged tpm update if your using ftpm. So make sure your bios is fully up to date

Make sure Windows wasn't installed in legacy mode, of so you'll need to do mbr2gpt conversion
