4. Remove problematic applications
If you’re having Hamachi errors, such as the tunneling problem or the VPN error, the issue might be caused by 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.

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.

6. Install the driver manually while Hamachi is installing
- Press Windows Key + X and choose Device Manager from the list.
- Locate LogMeIn Hamachi Virtual Ethernet Adapter, right-click it, and choose Update driver from the menu.
- Select Browse my computer for driver software.
- Now head over to the Hamachi installation directory, by default it should be:
C:\Program Files (x86)\LogMeIn Hamachi
Note: 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.
7. Use a different 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.
8. 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.
9. Disable Windows Firewall
- Search for windows firewall and select Windows Defender Firewall from the list.
- Click on Advanced settings from the menu on the left.
- Select Windows Defender Firewall Properties.
- Go to the Domain Profile tab and set Firewall state to Off.
- Go to the Private Profile and Public Profile tabs and do the same. Lastly, click Apply and OK to save changes
Note: Disabling the firewall isn’t the best choice in terms of safety, but if Hamachi works after you do that, the issue is probably related to one of your firewall settings, so you’ll need to manually find and change it.
Several users reported that port 25565 was the problem, so to fix this issue, be sure that the port 25565 is open on the 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.
