Solution 1 – Check your antivirus

Hamachi VPN error Windows 10

According to users, the cause for Hamachi errors can be your antivirus. Sometimes your antivirus can block Hamachi, so be sure to check its settings and make sure that Hamachi is allowed to run. If Hamachi isn’t blocked, you might want to try disabling certain features or disable your antivirus altogether.

In case the problem is still there, your last option would be to remove your antivirus completely from your PC. Even if you remove your antivirus, your PC will remain protected by Windows Defender, so there’s no need to worry about your safety.

If removing the antivirus solves your problem, this might be a good time to consider switching to a different antivirus solution. If you’re looking for a new antivirus that won’t interfere with your system and other applications, we strongly advise that you try out Bitdefender.

Bitdefender has released the 2019 version and it is full of the newest security features. You will have a double-engine scan, VPN, encryption and permanent signature database update. We recommend you to check its plans.

Solution 3 – Remove problematic applications

If you’re having Hamachi errors, such as the tunneling problem or the VPN error, the issue might be caused by a third-party software. Sometimes VPN clients can interfere with Hamachi and that can lead to this and many other problems.

To fix the problem, it’s advised to find and remove your current VPN client. Users reported that Dell VPN client caused this problem to appear, but after removing it, the issue was resolved. Bear in mind that other software can cause this issue to appear, and not just your VPN client.

If your VPN client was the problem, you should consider using a different VPN client. If you want a good and user-friendly VPN client that won’t interfere with your system, we strongly suggest that you try out Cyberghost VPN.

Solution 4 – Reinstall Hamachi

Sometimes Hamachi errors can be caused by a corrupted installation, and if that happens, the best course of action would be to reinstall Hamachi. This is fairly simple to do, but in order to completely reinstall Hamachi, it’s advised that you use uninstaller software.

In case you don’t know, uninstaller software such as IObit Uninstaller can completely remove the desired application from your PC. Unlike the regular uninstall process, the uninstaller software will remove all files and registry entries associated with Hamachi.

After Hamachi is completely removed, it will be as if it was never installed on your PC. Now you just have to download and install the latest version and the issue should be completely resolved.

Solution 5 – Install the driver manually while Hamachi is installing

Sometimes Hamachi errors can be caused by missing drivers, and if you’re getting a tunneling problem or VPN error, the issue might be the missing drivers. Several users reported that Hamachi installation hangs while installing a virtual network driver, and in order to fix this problem, you need to install this driver manually. To do that, you need to do this quickly while the installation is stuck:

  1. Press Windows Key + X to open Win + X menu. Now choose Device Manager from the list.

  2. Locate LogMeIn Hamachi Virtual Ethernet Adapter, right-click it and choose Update driver from the menu.
  3. Select Browse my computer for driver software.

  4. Now head over to the Hamachi installation directory, by default it should be C:Program Files (x86)LogMeIn Hamachi.

Once you select this directory, your PC should scan it and install the missing driver. Once that is done, the latest driver will be installed and the installation will complete successfully. Bear in mind that you’ll need to update the driver quickly in order for this to work, so it might be a good idea to have the Device Manager open while installing Hamachi.

Solution 6 – Use a different installer

According to users, sometimes Hamachi errors can be caused by your installer. This is an unusual cause, but several users reported that they fixed the problem simply by removing Hamachi and using the different setup file to install it.

Users claim that they downloaded the installer from a different source that is not Hamachi’s official website, and by doing so the problem was resolved. We don’t know how reliable this method is, but many users claim that it works, so feel free to try it out.

Solution 7 – Try using an older version of Hamachi

In some instances, Hamachi errors can appear if you’re using the latest version. When it comes to software, usually it’s a good practice to use the latest software since it offers the latest features and updates.

However, sometimes certain features can be buggy, and that can lead to this and many other errors. To fix this problem, some users suggested to roll back to the older version of Hamachi and check if that helps.

To do that, remove the current version and then download and install the older version. To find an older version, you might have to use third-party sources. Once you download the older version, install it and check if that solves your problem.

Bear in mind that Hamachi will check for the latest version once you install it, so be sure to prevent it from downloading the latest updates.

Solution 8 – Disable Windows Firewall

If you’re having Hamachi errors, such as the yellow triangle, the problem might be related to your firewall. To check if your firewall is the issue, some users are suggesting to disable it temporarily and check if that solves your problem. To do that, follow these steps:

  1. Press Windows Key + S and enter windows firewall. Select Windows Defender Firewall from the list.
    Hamachi error this network does not exist
  2. When Windows Defender Firewall opens, click on Advanced settings from the menu on the left.
  3. A new window will now appear. Select Windows Defender Firewall Properties.

  4. Go to the Domain Profile tab and set Firewall state to Off. Now go to the Private Profile and Public Profile tabs and do the same. Lastly, click Apply and OK to save changes

After doing that, your firewall should be completely disabled. We have to mention that disabling the firewall isn’t the best choice in terms of safety, but if Hamachi works after you disable your firewall, the issue is probably related to one of your firewall settings, so you’ll need to manually find and change the problematic setting.

Several users reported that port 25565 was the problem, so to fix this issue, be sure that the port 25565 is open in Incoming rules page. After making this change, the problem should be resolved and Hamachi will start working again.

Hamachi errors can cause many problems on your PC, but in most cases these problems are caused by your firewall settings, corrupted installation or other applications. However, we hope that you managed to fix this problem by using one of our solutions.
