Valorant Not Launching: Causes, Fixes, and Troubleshooting Guide (Part 2)

Update Windows

An outdated version of Windows can cause compatibility issues with Valorant and Riot Vanguard. Keeping your operating system up to date ensures you have the latest security patches, bug fixes, and performance improvements.

To update Windows:

1. Open Settings.
2. Select Windows Update.
3. Click Check for updates.
4. Download and install any available updates.
5. Restart your computer after the installation is complete.

Once your PC restarts, launch Valorant again to see if the issue has been resolved.

Check Secure Boot and TPM (Windows 11)

On Windows 11, Riot Vanguard may require Secure Boot and TPM 2.0 to be enabled. If either feature is disabled, Valorant may refuse to launch.

To check:

• Press Windows + R, type msinfo32, and press Enter.
• Look for Secure Boot State.
• Check that TPM is available by running tpm.msc.

If Secure Boot or TPM is disabled, you may need to enable them in your computer’s BIOS or UEFI settings. Refer to your motherboard or laptop manufacturer’s documentation for specific instructions.

Allow Valorant Through Windows Firewall

Windows Firewall may block Valorant or Riot Client from accessing the internet.

To allow the game:

1. Open Windows Security.
2. Select Firewall & network protection.
3. Click Allow an app through firewall.
4. Find Valorant, Riot Client, and Riot Vanguard.
5. Ensure both Private and Public network boxes are checked.

Restart the game after saving the changes.

Perform a Clean Boot

Background services from third-party software can interfere with Valorant.

To perform a clean boot:

1. Press Windows + R, type msconfig, and press Enter.
2. Open the Services tab.
3. Tick Hide all Microsoft services.
4. Click Disable all.
5. Open the Startup tab and disable unnecessary startup applications.
6. Restart your computer.

If Valorant launches successfully, re-enable services one by one to identify the conflicting program.

Reinstall Riot Client and Valorant

If none of the previous methods work, reinstalling the game may resolve corrupted installation files.

Steps:

1. Uninstall Valorant.
2. Uninstall Riot Vanguard.
3. Remove the Riot Client.
4. Restart your computer.
5. Download the latest installer from the official Riot Games website.
6. Install the Riot Client and then reinstall Valorant.

A fresh installation often fixes persistent launch problems.

Check Internet Connection

Although Valorant should open without a match connection, network issues can sometimes prevent the Riot Client from working correctly.

Try these tips:

• Restart your router.
• Use a wired Ethernet connection if possible.
• Avoid VPNs or proxy servers.
• Close bandwidth-heavy downloads.
• Restart your modem if your connection is unstable.

A stable internet connection improves login reliability and game performance.

Additional Troubleshooting Tips

If Valorant still does not launch, try these additional solutions:

• Free up storage space on your system drive.
• Disable unnecessary overlays such as Discord or GeForce Experience.
• Close CPU-intensive applications before starting the game.
• Scan Windows for corrupted system files using the System File Checker (SFC) tool.
• Check your computer for malware using trusted antivirus software.
• Ensure your graphics card supports the latest DirectX version required by the game.

These steps can help eliminate less common causes of launch failures.

Tips to Prevent Future Launch Problems

To minimise the chances of Valorant failing to launch in the future:

• Keep Windows updated.
• Update graphics drivers regularly.
• Avoid force-closing Riot Vanguard.
• Install game updates promptly.
• Restart your PC occasionally.
• Maintain enough free disk space.
• Avoid downloading unofficial game modifications.
• Use reliable antivirus software without blocking Riot services.

Preventive maintenance can reduce crashes and improve overall gaming stability.
