Fix 1. Enable TPM
Trusted Platform Module (TPM) is a security feature built into your computer's motherboard that stores encryption keys and ensures the integrity of your system. Valorant's new security standards require it to be active. To enable TPM:
- Open your system BIOS. You can usually do this by restarting your computer and pressing a specific key (like F2, F10, or Del - it depends on your motherboard or laptop manufacturer) as it boots up.
- Look for an option related to TPM, likely found under a Security or Advanced tab.
- Enable the TPM option.

- Your computer will restart with TPM enabled.

Now, you should check whether the TPM feature is enabled as follows:
- Press Win + R on your keyboard to open the Run dialog.
- Type tpm.msc in the box and hit Enter or click OK.
- If you see the "Compatible TPM cannot be found" message, TPM does not exist on your system.

Fix 2. Enable Secure Boot
Secure Boot is a security standard developed by members of the PC industry to help ensure that your PC boots only trusted software. This is another requirement for playing Valorant. To enable Secure Boot:
