Fix: Hamachi Service Stopped on Windows 10

A lot of LogMeIn Hamachi users are reporting that they are unable to use the software. In most affected users cases, a self-diagnostic popup appears when the software is started where the error is identified as a stopped Hamachi service. The issue is mostly encountered to occur on Windows 10, but there are reports of it occurring on Windows 8.

Hamachi Error Service not Started

What is causing the ‘Hamachi Service Stopped’ error on Windows 10?

We researched this particular error message by looking at a lot of user reports. We successfully managed to recreate the issue on our testing machines and analyzed the repair strategies that other affected users have deployed to resolve the issue.

Based on what we gathered, there are several common  culprits that are known to trigger this particular error message:

  • Hamachi app doesn’t have administrative privileges – The issue is often occurring because, for some reason or another, the Hamachi app doesn’t have administrative privileges. In this case, you can resolve the error by forcing the application to run with admin privileges.
  • The Windows Management Service is disabled – Hamachi depends a lot on the Windows Management Instrumentation service (WMI). If this service is configured to stay disabled, this particular error will occur.  In this case, starting the service should resolve the issue.
  • Missing dependencies for Workstation – A couple of users have reported that the issue was resolved after they used an elevated Command Prompt to configure Hamachi’s dependencies to add Workstation. This is typically reported to occur if the user upgraded to Windows 10 from an older Windows version.
  • The LogMeIn Hamachi Tunneling Engine is not configured properly – There are cases where the issue was confirmed to occur because the startup type of the service was not set to Automatic. This can be resolved quite easily by taking a trip to the Services screen.
  • Third party security interference – There are a couple of overprotective AV/firewall suites that are known to conflict with LogMeIn Hamachi. Uninstalling the overprotective suite or establishing exceptions to Hamachi should resolve the issue in this case.
  • Log-off or power-cycling is disabling the Hamachi service – This is a common scenario on computers that need to log-off or power-cycle frequently. You can get around this inconvenience by creating a startup task to safeguard against these scenarios.

  4. With the service enabled, start LogMeIn Hamachi again and see if the issue has been resolved. If the answer is no, continue with the next method below.

Method 3: Changing dependencies to add Workstation

The issue might also be occurring because the Windows Management Instrumentation (WMI) service does not have the required dependencies to function properly.

In those instances where the WMI service was enabled but LogMeIn Hamachi was still not working, some users have reported that the issue was resolved after they changed some dependencies to add Workstation from an elevated Command Prompt.

Here’s a quick guide on how to do this:

  1. Press Windows key + R to open up a Run dialog box. Then, type “cmd” and press Ctrl + Shift + Enter to open up an elevated Command Prompt window. When prompted by the UAC (User Account Control), choose Yes to grant administrative privileges.

    Note: If you decide to type the command, note that there’s a space after ‘=’, but no space before it.

  3. Restart your computer and see if the error has been resolved at the next startup.

If you’re still encountering the ‘Hamachi Service Stopped’ error, move down to the next method below.

Method 4: Configuring the LogMeIn Hamachi Tunneling service

Some affected users have reported that they managed to resolve the issue by setting the startup type of LogMeIn Hamachi Tunneling Engine service to Automatic and allowing the service to log in as the local system account. Upon a restart, most affected users have reported that the issue was resolved.

Method 5: Uninstall 3rd party security suite (if applicable)

As some users have suggested, the issue can also be caused by an overprotective 3rd party security suite. Several users encountering the same error have reported that the issue was no longer occurring after they uninstalled the 3rd party firewall/antivirus.

If you are fond of your security solution, you can probably resolve the conflict by establishing an exception in your Firewall/antivirus settings (excluding all Hamachi services from the scan). However, the steps of doing so will be different depending on the AV service that you’re using.

Once you’ve dealt with your third-party security software, restart your computer and see if the ‘Hamachi Service Stopped’ error is resolved at the next startup.

If you’re still encountering the issue, move down to the next method below.

Method 6: Creating a Startup task to safeguard against log-off or power-cycle

It’s a well-known fact that Hamachi (and dependent) services will stop if you log-off or power-cycle while the software is running. This might be annoying for some users since the quickest solution is to just restart and let the involved components to refresh again.

However, there’s one way to automate the whole process. You can establish a safeguard measure by adding an automatic repeating task that launches a .cmd file at every startup. This will spare you from the trouble doing constant restarts.

Here’s what you need to do:

  1. Press Windows key + R to open up a Run dialog box. Then type “notepad” and press Ctrl + Shift + Enter to open a new notepad window as Administrator.  When prompted by the UAC (User Account Control), choose Yes to grant administrative privileges.
    Opening a new Notepad window

    Note: Opening as an administrator is Important. The procedure will not work if you follow the instructions from a regular window.

  2. In the newly opened notepad window, type the following commands in this exact order:
    net stop Hamachi2Svc
    net start Hamachi2Svc
    start "X:\Filepath\LogMeIn Hamachi\hamachi-2-ui.exe"
    exit

    Note: Keep in mind that the one line three, the first part (*X:\Filepath*) is simply a placeholder. Replace it with the appropriate drive letter and path. In the end, the command should look like this: start “C:\Program Files (x86)\Hamachi-2-ui.exe”

  3. Once the code is configured, go to File > Save As. Then, in the Save As window, set the name of the file as HamachiStart.cmd and change the Save as type to All Files. Then, navigate to C:\Windows\System32 and hit Save to store the newly created CMD file in the System 32 folder.
