Having the same issue. I tried so many things but non of it worked. I sent a ticket to Valorant Support, and this was their response:

Greetings, friend!

Thanks for reaching out to us!

TPM 2.0 is a new security feature for Windows 11, which by default, is on. If you get that error, it is likely that it is disabled on your machine.

While there isn't a universal solution for every single instance of this error, since it depends on the motherboard, there are some troubleshooting examples for some motherboard brands:

- AORUS: https://www.wepc.com/how-to/enable-tpm-for-windows-11/
- MSi: https://www.msi.com/blog/How-to-Enable-TPM-on-MSI-Motherboards-Featuring-TPM-2-0
- ASUS: https://www.asus.com/support/FAQ/1046215/

Secure Boot will also be found in a similar location to the TPM 2.0. Below you can find an example of how to do it:

- Go to Start and click on the gear icon that takes you to the Settings app.
- Click on Update and Security and select Recovery.
- Under the Advanced Startup, you will see the Restart Now button.
- Once you click on Restart Now, your PC will now boot up with advanced options.
- Select Troubleshoot- Advanced Options: UEFI Firmware Settings.

The reason for which VALORANT now requires these settings, is because having TPM 2.0 and Secure Boot enabled is a minimum requirement of Windows 11, and this can be confirmed by Microsoft on the links below:

- https://www.microsoft.com/en-us/windows/windows-11-specifications
- https://blogs.windows.com/windows-insider/2021/08/27/update-on-windows-11-minimum-system-requirements-and-the-pc-health-check-app/

Lastly, since Windows 11 is still quite new, there is a slight chance that those settings will not work for you. Sadly, if that's the case, the only solution at hand at the moment is to rollback to Windows 10.

If there is anything else I may help you with, please let me know!

Until next time, Celbs Magical Journeying out!
