There is nothing more frustrating than launching your favorite tactical shooter only to find that your Valorant cannot update. Whether you are staring at a progress bar that refuses to move or receiving a vague error message from the Riot Client, these update hurdles prevent you from jumping into the fray. Most of these issues stem from network instabilities, administrative permission conflicts, or glitches within the Riot Vanguard anti-cheat system.

Basic Troubleshooting Steps
Before diving into complex system registry edits or network configurations, it is essential to rule out the simplest causes. Often, a minor software hang can block the Riot Client from communicating with the update servers.
First, perform a complete restart of your system. This clears the system cache and terminates any zombie processes that might be locking the game files. If a restart doesn’t work, check your available disk space. Valorant requires a significant amount of overhead to unpack update files; if your drive is nearly full, the update will stall indefinitely. Ensuring your pc performance is optimized by freeing up at least 10-20GB of space can often resolve the issue immediately.
Additionally, check if you have multiple instances of the Riot Client running in the background. Open the Task Manager (Ctrl + Shift + Esc), locate any processes related to Riot or Valorant, and select End Task. This ensures a clean slate for the updater to initiate the patching process without conflict.
Network Connectivity Fixes
Since updates require a stable handshake between your PC and Riot’s servers, network timeouts are a common culprit. If the update is stuck at a specific percentage, your connection might be dropping packets or being blocked by a DNS error.
Flushing Your DNS Cache
Over time, your DNS cache can become corrupted, leading to resolution errors. To fix this, open the Command Prompt as an administrator and type ipconfig /flushdns. This forces your computer to refresh its connection to the servers, which often clears the path for the Valorant update to proceed.
Changing DNS Servers
If your ISP’s default DNS is unstable, switching to a public DNS like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1) can significantly improve connectivity. To do this, navigate to your Network and Sharing Center, enter your adapter settings, and manually assign the DNS addresses in the IPv4 properties.
Disabling VPNs and Proxies
While VPNs are great for privacy, they can introduce latency or be flagged by Riot’s security systems, causing the update to fail. Disable any active VPN or proxy server and attempt to launch the client again using your direct local connection.
Administrative and Permission Solutions
The Riot Client needs specific permissions to modify files within the Program Files directory. If the client lacks these permissions, it will be unable to overwrite old files with new patches, resulting in a ‘cannot update’ loop.
Running as Administrator
Right-click the Riot Client shortcut on your desktop and select Run as Administrator. This grants the application the necessary elevation to write data to protected system folders. If this works, you can make it permanent by right-clicking the icon, going to Properties > Compatibility, and checking the box for ‘Run this program as an administrator’.
Checking Folder Read-Only Attributes
Sometimes, the game folder becomes set to ‘Read-Only’ due to a system crash or antivirus interference. Navigate to the folder where Valorant is installed, right-click the folder, select Properties, and ensure the Read-only attribute is unchecked. Apply this change to all subfolders and files to ensure the updater can modify the game data.
Riot Vanguard and Client Repair
Unlike most games, Valorant relies on Riot Vanguard, a kernel-level driver. If Vanguard is corrupted or out of date, it can block the rest of the game from updating because the two must be synchronized for security reasons.
Reinstalling Riot Vanguard
If the update is stuck, try removing Vanguard specifically rather than the whole game. Go to Add or Remove Programs, find Riot Vanguard, and uninstall it. Once removed, restart your computer and launch the Riot Client. The client will detect that Vanguard is missing and trigger a fresh, clean installation of the anti-cheat, which often bypasses the update glitch.
Clearing the Riot Client Cache
Corrupted temporary files in the client cache can mislead the updater into thinking the game is already updated or completely broken. Navigate to the AppData folder (type %localappdata% in the Windows search bar), find the Riot Games folder, and delete the Install** and Riot Client cache folders. This forces the client to re-verify the game’s integrity upon the next launch.
Advanced System Troubleshooting
If none of the above steps work, the issue may lie deeper within the Windows OS or conflicts with third-party security software.
Firewall and Antivirus Exclusions
Aggressive antivirus software or the Windows Defender Firewall may mistake the update process for a malicious injection. To fix this, add the entire Riot Games folder and the RiotClientServices.exe to your antivirus exclusion list. This prevents the software from scanning and blocking the update stream in real-time.
Running System File Checker (SFC)
System-level corruption can interfere with how applications install updates. Open the Command Prompt as an administrator and run the command sfc /scannow. This tool scans for corrupted system files and repairs them, ensuring that the environment the Riot Client operates in is stable.
Updating Windows and Drivers
Ensure your Operating System is fully up to date. Riot frequently updates its security requirements, and an outdated version of Windows 10 or 11 may lack the necessary API updates required for the latest Valorant patch to execute correctly.
Conclusion
Dealing with a Valorant cannot update error is usually a matter of identifying where the communication break is occurring. Whether it is a DNS glitch, a Vanguard conflict, or a simple lack of administrator privileges, following a systematic approach—from basic restarts to advanced system repairs—will almost always resolve the problem. By maintaining a clean system and ensuring your network is optimized, you can minimize these interruptions and get back to climbing the ranks.
Frequently Asked Questions
Why is my Valorant update stuck at 0% or a specific percentage?
This is typically caused by a network timeout or a file permission error. Try flushing your DNS or running the Riot Client as an administrator to allow the download to resume.
Do I need to reinstall the entire game if the update fails?
No, a full reinstall is a last resort. Try uninstalling only Riot Vanguard or clearing the client cache first, as these are the most common points of failure.
Can a slow internet connection cause the ‘cannot update’ error?
While slow speeds cause longer wait times, a complete failure to update is usually due to packet loss or firewall blocks rather than raw speed. Check your connection stability and disable any active VPNs.
What should I do if the ‘Update’ button in the Riot Client is missing?
This often indicates a synchronization error between your client and the server. Restart the client, check for Windows updates, and ensure your system time and date are set to ‘Automatic’.
Will changing my DNS settings affect other games or apps?
Switching to Google or Cloudflare DNS generally improves connection stability and speed across all your internet activities and is safe for all other software on your PC.
