FIXED: Valorant Unsupported Operating System [Windows 11]

Sometimes, despite enabling Secure Boot and the system supporting TPM 2.0, the basic system requirements, Windows 11 users face the “Valorant unsupported operating system” error when launching the game. There could be several reasons you may get stuck in this annoying situation, such as compatibility or driver issues, bugs, overclocking graphics cards, faulty installation, or game files.

This is the error message you will see on your screen:

Key Takeaways

• Valorant gamers sometimes encounter OS support errors, which makes them unable to launch the game on their Windows 11 systems.
• Several factors could be behind the error, including corrupt game files, outdated graphics drivers, and compatibility issues between the program and the system.
• Fix the error by updating the graphics driver, enabling secure boot, or reinstalling and running the game as an admin.
• Always power cycle your PC and restart the game before diving into any technical fixes.

Update Graphics Card Driver

Per my testing, an outdated graphics card driver may lead to Valorant launch errors in Windows 11. Outdated drivers not only cause system functionality issues but can also result in failure to access various features and applications, as is happening in our case. To eliminate the issue, you need to update the graphics driver.

Run Valorant As An Administrator

Granting administrator privileges to the program can resolve the Valorant unsupported OS issue. Doing so provides the program with all the required rights and access to the info and files necessary to launch it without any hindrance.

Here’s how to run Valorant as an admin:

1. Press the Windows key > Type Valorant > Right-click on Valorant > Open file location. 
2. Right-click Valorant shortcut > Properties > Open Compatibility tab > Mark the Run this program as an administrator checkbox > Apply > OK.

   

Close All Riot-Related Processes

A bug in any Riot-related process may become the causing factor behind the Valorant not working. 

Here’s how to stop all Riot-related processes:

1. Open Search Bar > Type Task Manager > head to Processes tab.
2. Look for Riot-related processes. You can identify them through the Valorant or Riot logo.
3. Click on each > Hit End task.
4. Right-click the Start button > Type Run > Enter %localappdata% > OK.
5. Go to View > Check the Hidden Items box.
6. Head to Valorant > Saved > Delete the config and log folders > Restart the system.

While this method worked flawlessly for me, I also noticed that it was being used by users on YouTube.

Reinstall Valorant

The best way to fix the error is by reinstalling Valorant. The system will replace the troublesome files, and the support bug will be resolved. So, I deleted the game and all its related files on my Windows 11 and reinstalled it a few minutes later. It resumed the gameplay for me.

Here’s how to perform the reinstallation:

1. Hit Windows key > Enter Add Or Remove Programs > Press Enter.
2. Look for Valorant in the list > Hit the three dots beside it > Uninstall.
3. After uninstallation, visit Valorant’s official website > Find the latest version > Download it > Install the game.

Enable TPM 2.0 And Secure Boot

You must have TPM 2.0 and Secure Boot enabled on your Windows 11. If, for any reason, these essentials are disabled or not fulfilled, then the Valorant support error may arise.

Here’s how to enable TPM 2.0 and Secure Boot:

1. Restart your system > Press Delete, F2, or F12 keys as per the brand of your PC when the manufacturer’s logo appears on the screen.
2. Go to BIOS Settings > Security Settings > Enable TPM Device labels, Trusted Program Module, or TPM Security.
3. Enable Secure Boot > Save and close the BIOS settings > Restart the PC.

   

I verified that the two crucial features were running on my Windows, and this was also the cause of the error for users on Reddit

Update Windows

Timely Windows update installation is crucial to keep the system running smoothly without causing security and program functionality issues. Install the latest Windows update if any pending system updates are available. Once the installation process finishes properly, try relaunching the game. 

Valorant will fail to launch on your Windows 11 if your system does not meet the essential requirements for the game and TPM 2.0 and Secure Boot are not enabled. Also, if you are using a pirated version of Windows, that might cause the error. Kindly install a genuine OS version and ensure that your computer meets the minimum system requirements (30FPS).
