Valorant is a popular tactical shooter from Riot Games, but like any PC game, it can sometimes refuse to start. You may click the Valorant icon and nothing happens, the Riot Client may open without launching the game, or Valorant may close immediately after starting.
The good news is that most Valorant not launching problems can be fixed without reinstalling the entire game. The cause can be an outdated Windows version, Riot Vanguard problems, corrupted game files, graphics drivers, background applications, or incorrect system settings.
In this guide, we will explain the most common reasons Valorant does not launch and the steps you can take to get the game working again.
Why Is Valorant Not Launching?
Before trying different solutions, it helps to understand what might be causing the problem.
Common reasons include:
- Riot Vanguard is not running correctly
- Corrupted Valorant or Riot Client files
- Outdated graphics drivers
- Pending Windows updates
- Riot Client glitches
- Background applications interfering with the game
- Antivirus or firewall blocking game components
- Incorrect permissions
- Problems with system security settings
- Compatibility issues after a Windows update
The exact cause can be different from one computer to another, so it is best to start with the simplest solutions first.
1. Restart Your Computer
A simple restart can fix temporary Windows and Riot Client problems.
Close Valorant and the Riot Client completely, then restart your computer. After Windows loads again, open Riot Client and try launching Valorant.
Restarting can clear temporary processes and allow Riot Vanguard and other required services to start correctly.
If Valorant launches after restarting, the issue may have been caused by a temporary software or service problem.
2. Run Riot Client as Administrator
Valorant may sometimes have problems accessing certain Windows resources.
Try running the Riot Client with administrator permissions.
Right-click the Riot Client shortcut and select Run as administrator. Then try launching Valorant.
If this solves the problem, you can check the application’s properties and configure it to run with administrator privileges when necessary.
However, avoid changing Windows permissions unnecessarily. Only use administrator access when it actually helps resolve the issue.
3. Check Riot Vanguard
Riot Vanguard is the security software used by Valorant. If Vanguard is not working correctly, the game may refuse to start.
After restarting your computer, look for the Vanguard icon in the Windows notification area. If Vanguard is not running correctly, Valorant may not launch.
You can also restart your computer because Vanguard may require a system restart after an installation or update.
If Vanguard appears to be damaged or incorrectly installed, reinstalling Vanguard can help.
To do this, uninstall Riot Vanguard through Windows settings, restart the computer, and then launch Valorant again. The Riot software can reinstall the required Vanguard components.
4. Update Windows
An outdated Windows installation can sometimes cause compatibility problems with modern games.
Open Settings > Windows Update and check for available updates. Install important updates and restart your computer if Windows asks you to do so.
Keeping Windows updated can also improve compatibility with graphics drivers, security components, and game software.
If Valorant stopped launching immediately after a Windows change, checking for additional updates may also be useful.
5. Update Your Graphics Driver
Graphics drivers play an important role in launching and running games.
If your NVIDIA, AMD, or Intel graphics driver is outdated or damaged, Valorant may fail to start or may close shortly after opening.
Visit the official website of your graphics hardware manufacturer and check for the latest driver that supports your GPU and version of Windows.
After installing the driver, restart your computer and try Valorant again.
If the problem started immediately after a driver update, checking whether the manufacturer provides another driver version may also be worthwhile.
6. Close Background Applications
Some background programs can interfere with games.
Examples include:
- Screen recording software
- Overlay applications
- Hardware monitoring tools
- Other game launchers
- Streaming applications
- Unnecessary system utilities
Close applications that you do not need before launching Valorant.
You can use Task Manager by pressing Ctrl + Shift + Esc to see running applications and background processes.
Do not end Windows system processes unless you know what they do. Focus on closing applications that you recognize and do not currently need.
7. Temporarily Check Antivirus and Firewall Settings
Security software can occasionally interfere with legitimate game files or services.
If Valorant suddenly stopped launching after an antivirus update or security configuration change, check whether the Riot Client, Valorant, or Vanguard components have been blocked.
Instead of permanently disabling security software, use its settings to check for blocked applications or create appropriate exceptions when necessary.
Windows Firewall settings can also be reviewed to make sure the Riot Client and Valorant are allowed to communicate normally.
Always keep your security software enabled whenever possible.
8. Repair or Reinstall the Riot Client
The Riot Client itself can sometimes experience corrupted or incomplete files.
If Valorant refuses to launch, restarting the Riot Client may not be enough. Check whether Riot provides a repair option for the installed game or client.
A repair process can replace damaged files without requiring you to manually remove everything.
If repair does not solve the problem, reinstalling the Riot Client may be another option.
Before reinstalling, make sure you know where your game is installed and understand which components will be removed.
9. Check Valorant Compatibility Settings
Windows compatibility settings can sometimes create unexpected problems.
Right-click the Valorant or Riot Client shortcut, open Properties, and review the Compatibility tab.
Avoid enabling random compatibility options unless you have a specific reason. Some settings can actually create new problems on modern versions of Windows.
If you previously changed compatibility settings, restoring them to their default configuration may help.
10. Check Your System Requirements
Valorant has relatively modest hardware requirements compared with many modern PC games, but your computer still needs to meet the game’s supported requirements.
Check whether your PC has:
- A supported Windows version
- Compatible graphics hardware
- Enough system memory
- Sufficient storage space
- Updated drivers
If your hardware or operating system does not meet the requirements, launching problems may occur.
11. Restart Riot Vanguard After Changes
After updating Windows, drivers, or Riot software, restart your computer before testing Valorant again.
This is particularly important when Vanguard has been installed, updated, or repaired.
A full restart allows required services to load properly and can resolve situations where the game cannot communicate correctly with Vanguard.
12. Reinstall Valorant as a Last Resort
If none of the previous solutions work, reinstalling Valorant may be necessary.
Before doing this, make sure your internet connection is stable and you have enough free storage for the installation.
Uninstall the game and required Riot components according to Riot’s current instructions. Restart Windows and install the latest version again.
Reinstalling takes longer than other troubleshooting methods, so it should generally be considered after simpler solutions have failed.

Final Thoughts
When Valorant is not launching, the problem can be caused by several different things, including Riot Vanguard, Windows updates, graphics drivers, corrupted files, background applications, or security settings.
Start with basic troubleshooting: restart your computer, check Riot Vanguard, update Windows, and make sure your graphics driver is current. If Valorant still does not open, check background applications, security software, the Riot Client, and system compatibility.
Most launch problems do not require replacing your computer or performing complicated changes. By working through these solutions one at a time, you can usually identify what is preventing Valorant from starting and get back into the game.
