Like many tech services and programs, Hamachi also faced challenges when it transitioned to Windows 10. Over the years, many users encountered the “VPN domain’s tap device is down” error. If you’re one of the affected users, do not panic. In this post, we are going to teach you how to fix the VPN Domain’s Tap Device is Down error.

  4. Reinstalling the drivers while Hamachi is running

Method 1: Running the Diagnostic Tool

When you’re wondering what to do if the VPN Domain’s tap device is down on Hamachi, the first thing you should turn to is the Diagnostic Tool. You will be able to identify the cause of the issue with the help of this built-in LogMeIn feature. If you see yellow exclamation marks beside the items, there are actions you must take to repair them. Follow the steps below to run LogMeIn’s Diagnostic Tool:

  1. Launch the LogMeIn Hamachi client.
  2. Go to Help, then click Diagnostic Tool.

Follow the on-screen instructions to get rid of the error. On the other hand, if you see that all the items have a green check mark beside them, it means that there are no issues with the components in your computer. Try restarting the application to resolve the issue.

Method 2: Reinstalling Hamachi

Another way to get rid of the error is by reinstalling the Hamachi service client on your computer. Remember to remove all the Hamachi-related files and drivers from your PC before proceeding with the installation process. Here are the steps:

  1. Go to your taskbar and click the Search icon.
  2. Type “Control Panel” (no quotes), then hit Enter.
  3. Click Uninstall a Program under the Programs section.
  4. Look for Hamachi, right-click it, then select Uninstall from the options.
  5. Do not forget to open Device Manager to remove all Hamachi-related virtual network adapters.
  6. Restart your computer, then download and install the latest version of Hamachi.
  7. If the error persists, try running the installation file without removing Hamachi first.
  8. Restart your computer.

Method 3: Uninstalling Recently Added Windows 10 Updates

According to some users, the error occurred after they had installed certain Windows 10 updates. After all, Hamachi was functioning perfectly until Microsoft rolled out new patches. So, we recommend uninstalling the updates you recently added to resolve the error. To do that, follow the steps below:

  1. On your keyboard, press Windows Key+I. This should launch the Settings app.
  2. Select Update & Security.
  3. Go to the left-pane menu, then select Windows Update.
  4. Now, go to the right pane and click Check for Updates.
  5. Click Uninstall Updates.
  6. Remove the updates you recently added, then restart your computer.

Method 4: Reinstalling the Drivers While Hamachi is Running

Some users claimed that reinstalling the LogMeIn virtual ethernet drivers while Hamachi is running helps in resolving the error. So, it would not hurt if you tried the same solution. Just go to Device Manager and remove all the associated network adapters. Reinstall them, then check if the error is gone.
