If you are encountering a Valorant unsupported operating system error message, it signifies that Valorant is detecting an aspect in your system that indicates the version of your Windows is not compatible with the game. This issue primarily arises from using Valorant in a compatibility mode.
Compatibility mode allows users to run VALORANT with different versions of Windows. This feature was designed to run older programs that are incompatible with the current version of Windows. Since VALORANT is a recent game, there’s no need to run it in compatibility mode.
1. Run VALORANT as an administrator
Running VALORANT with inappropriate permissions also causes the VALORANT unsupported operating system error. Therefore, start by running it as an administrator, which will grant the necessary permissions to access the files and information required to run VALORANT properly. To do so, follow the steps:
- Right-click VALORANT and select Properties. If you don’t have a shortcut created, press the Windows key and type VALORANT.
- Here, right-click VALORANT and select Open file location.
- This will take you to the location where the VALORANT shortcut is located.
- Right-click on it and go to Properties.
- Then, go to Compatibility and tick Run this program as an administrator.
- Once done, click Apply and click OK to save the settings.
- Try launching the VALORANT and see if you can launch it.
2. Disable Compatibility Mode
As previously discussed, compatibility mode is typically used for running programs with older versions of Windows. However, VALORANT cannot operate with older versions, even when the compatibility settings are adjusted on the latest version. This holds particularly true when the user encounters this specific error. As a result, we should attempt to disable compatibility mode by following these steps:
- Access the Properties by right-clicking VALORANT. If you don’t have a shortcut, open the Start Menu and type VALORANT.
- Right-click on it and click Open file location.
- Here, right-click VALORANT and select Properties.
- Now go to the Compatibility tab and untick Run this program in compatibility mode for.
- Then, click Apply and click OK to save the settings.
- Try launching VALORANT to verify whether the error is fixed or not.
3. Update Windows
If you have an outdated or incompatible version of Windows, you will have to update your Windows. Otherwise, you cannot play VALORANT unless you upgrade your Windows version.
You should have at least Windows 10 version 1803 or above. Any Windows version before that won’t work. To check the Windows version, press the Win + R keys. Type winver in the input box and click OK. Here, you will see the Windows version. If it is outdated or incompatible, try updating Windows by following the steps:
- Press the Windows key and type Check for updates.
- Hit Enter to navigate into the Windows settings.
- Then, click Check for updates to find the pending available updates.
- Then, click Download and install to install the updates.
- Finally, restart your computer and see if the error is resolved.
4. Reinstall Riot Vanguard
Riot Vanguard is an anti-cheat program that runs in the background to monitor the programs and services running on your computer. This helps prevent the cheaters who are taking unfair advantage by using hacks in the game. However, when there is a problem with the Riot Vanguard or its services, VALORANT also refuses to launch by displaying different error messages. Therefore, try reinstalling the Riot Vanguard to fix this error.
To do so, follow the steps:
- Open the Run Program by pressing the Win + R keys.
- Here, type appwiz.cpl and click OK to navigate into the Apps & features of the control panel.
- Find the Riot Vanguard and double-click on it to uninstall.
- Once done, launch VALORANT to install the Riot Vanguard.
- Finally, restart your computer for the Riot Vanguard to be initialized. Then, see if the error is fixed.
5. Make sure you have TPM 2.0 and secure boot enabled
If you have Windows 11, you should make sure that you have TPM 2.0 and secure boot enabled from the motherboard bios settings. Secure boot is a feature in bios that helps prevent the malicious from executing when the computer boots up. While the TPM 2.0 is a chip in the motherboard or processor used to store the sensitive information. VALORANT requires both TPM 2.0 and Secure boot to be enabled in order to run VALORANT on Windows 11.
Most PCs manufactured in the last five years support TPM and Secure Boot. However, if your motherboard doesn’t support any of them, you will have to downgrade your Windows version to 10 in order to play VALORANT. Follow the steps to check whether the TPM 2.0 and secure boot is enabled or not.
To enable the TPM 2.0 and secure boot, you will have to access the motherboard bios settings.
- Turn off your system completely. Then, turn it on back.
- As soon you see the manufacturer’s logo, start pressing the key that leads you to the motherboard bios settings. Usually, the keys are F2, Delete, or F12 to enter in the bios settings.
- Once you have accessed the motherboard bios settings, go to Security Settings and find the option with the label TPM Device, TPM Security, or Trusted Program Module.
- Once done, enable it. Then, find the Secure Boot option in the security settings or boot settings and enable it as well.
- Once done, save and exit the motherboard bios.
- Your PC will restart. Once done, check if you can play VALORANT.
6. Reinstall Valorant
If you are still facing the error, it could be due to the corruption in the VALORANT files. In this case, you can try reinstalling the VALORANT to ensure the corrupted files are not causing the issue. Simply follow the steps to proceed with the reinstallation of VALORANT.
- Press the Win key and type Add or remove programs.
- Hit Enter to navigate into the settings.
- Find VALORANT and click the three dots.
- Then, click Uninstall and again Uninstall to remove the VALORANT.
- Once done, download and install VALORANT from the official site.
You might not get rid of this error message even after reinstalling VALORANT. This is because the error occurs due to the incompatibility of the Windows version. Therefore, you should try reinstalling Windows from the Microsoft website rather than finding other ways to fix this issue, as we tried every possible solution.
