That message is Valorant’s anti‑cheat (Vanguard) telling you it won’t run unless your system is using UEFI firmware with Secure Boot enabled and, usually, TPM 2.0 as well.
What the message means
- Vanguard checks your PC’s firmware mode (UEFI vs Legacy/CSM), Secure Boot state, and often TPM 2.0 status before letting you play.
- If any of these are off (Legacy/CSM enabled, Secure Boot off, or TPM off/not initialized), you see “This version of Vanguard requires UEFI Secure Boot to be enabled in order to play.”
Typical fix steps (high level)
Exact wording and menus differ by motherboard/PC brand, but the general requirements are:
- Firmware/boot mode set to pure UEFI, with CSM/Legacy boot fully disabled.
- Secure Boot set to Enabled (often under Security, Boot, or Windows OS Configuration in BIOS/UEFI).
- TPM 2.0 (Intel PTT or AMD fTPM) enabled under a Security/Trusted Computing/TPM menu.
After changing these, you usually need to save and exit BIOS, let Windows boot normally, and then restart Valorant so Vanguard can re‑initialize.
If you already enabled Secure Boot
Even when everything looks correct, some people still get the error; common workarounds include:
- Toggling Secure Boot off, saving and rebooting, then turning it back on and rebooting again, which can re‑register keys on some systems.
- Resetting BIOS to defaults, then re‑configuring UEFI mode, Secure Boot, and TPM 2.0 from scratch.
If you tell what motherboard or laptop model you have and whether Windows is installed in UEFI or Legacy mode, a more precise step‑by‑step can be given.
