How to Fix TeamViewer Not Working on Windows 11: Step-by-Step Solutions

TeamViewer is a popular remote desktop application that allows users to connect and control computers from anywhere. However, sometimes it may stop working properly on Windows 11. This can be frustrating if you rely on it for work or personal use.

Fortunately, many common issues with TeamViewer can be fixed quickly with simple steps. This guide will walk you through easy solutions to get TeamViewer running smoothly again on your Windows 11 PC.

Whether TeamViewer won’t start, fails to connect, or shows error messages, these step-by-step instructions will help you troubleshoot and resolve the problem without needing advanced technical skills.

Let’s begin with some quick checks before moving into detailed fixes.

Quick Note: Prerequisites and Initial Checks

  • Check your internet connection: TeamViewer requires a stable internet connection. Make sure your PC is connected and working online.
  • Verify TeamViewer version: Older versions might not be fully compatible with Windows 11. Ensure you are using the latest version.
  • Restart your computer: Sometimes a simple reboot resolves temporary glitches affecting TeamViewer.
  • Confirm TeamViewer service status: Ensure the TeamViewer service is running on your computer for the app to function correctly.

Step 1: Restart the TeamViewer Application

Often, problems arise due to temporary software glitches. Closing and reopening TeamViewer can clear these issues.

  1. Click the Close (X) button on the TeamViewer window to exit the app.
  2. Open the Task Manager by pressing Ctrl + Shift + Esc.
  3. Look for any running processes named TeamViewer.exe. If found, right-click and select End Task.
  4. Restart TeamViewer by clicking its shortcut on your desktop or searching in the Start menu.

Restarting ensures no background instances conflict with the app’s normal operation.

Step 2: Update TeamViewer to the Latest Version

Running an outdated version of TeamViewer can cause compatibility issues with Windows 11 features.

  1. Open TeamViewer and go to the menu by clicking Help in the top toolbar.
  2. Select Check for new version.
  3. If an update is available, follow the on-screen instructions to download and install it.
  4. After updating, restart your computer to apply changes fully.

Keeping TeamViewer updated ensures you have the latest bug fixes and security patches, which improve performance.

Step 3: Check and Restart the TeamViewer Service

TeamViewer relies on a Windows service to operate properly. Sometimes this service can stop or fail.

  1. Press Windows + R to open the Run dialog box.
  2. Type services.msc and press Enter to launch the Services window.
  3. Scroll down and find TeamViewer in the list.
  4. Right-click on TeamViewer and choose Restart.
  5. If the service is stopped, right-click and select Start.

Restarting the service refreshes the background processes TeamViewer needs to connect and communicate.

Step 4: Adjust Windows Firewall and Antivirus Settings

Windows Firewall or third-party antivirus software may block TeamViewer’s network access, preventing connections.

  1. Open Windows Security by searching for it in the Start menu.
  2. Go to Firewall & network protection.
  3. Click on Allow an app through firewall.
  4. Find TeamViewer in the list and ensure both Private and Public boxes are checked.
  5. If TeamViewer is missing, click Allow another app, locate the TeamViewer executable (usually in C:Program FilesTeamViewer), and add it.

For antivirus software, open its control panel and look for application or network exceptions to whitelist TeamViewer.

Step 5: Reinstall TeamViewer

If the above steps don’t fix the issue, a fresh installation might help repair corrupted files or settings.

  1. Press Windows + I to open Settings.
  2. Go to Apps > Installed apps.
  3. Find TeamViewer and click Uninstall.
  4. After uninstalling, restart your PC.
  5. Download the latest TeamViewer installer from the official website (teamviewer.com).
  6. Run the installer and follow prompts to complete installation.

Reinstalling ensures you start with a clean, fully functional version of TeamViewer.

Step 6: Check Network Settings and Proxy Configuration

TeamViewer requires proper network configuration. If you use a proxy or VPN, it might interfere with connections.

  1. Open TeamViewer and go to Extras > Options.
  2. Select the Advanced tab and scroll down to Network settings.
  3. Check the proxy settings. If you don’t use a proxy, make sure No proxy is selected.
  4. If you use a proxy or VPN, verify that they allow outgoing connections on TeamViewer’s required ports (usually TCP 5938).

Incorrect proxy settings can block TeamViewer from establishing remote sessions.
