How To Fix Windows 10 Hamachi Service Stopped Error

LogMeIn Hamachi  is a VPN application that allows links to be established between computers that are behind a NAT firewall without the need for any reconfiguration. Basically, what this application does is it connects computers over the internet by emulating the connection that would exist if the computers were connected on LAN. Although this is a solid application there are instances when certain issues can occur. In this latest installment of our troubleshooting series we will tackle the windows 10 Hamachi service stopped error.

Fixing the Hamachi service stopped error on Windows 10

Before performing the recommended troubleshooting steps for this particular problem I suggest that you try restarting your computer first. This will refresh the operating system as well as remove corrupt temporary data and is quite effective in fixing most software related issues.

There are several factors that can cause this problem ranging from a service that has stopped running to a third party software interference. Listed below are the recommended troubleshooting steps you need to do to fix the problem.

Run Hamachi as an administrator

The first thing you will need to do is to run Hamachi as an administrator. Right-click on the LogMeIn Hamachi executable and click on Run as Administrator. If the issue gets fixed then you will want to make this a permanent setting. Right-click on the LogMeIn Hamachi executable and go to Properties. Go to the Compatibility tab and check the box associated with Run this program as an administrator. When you hit apply your computer will now be configured to launch Hamachi with administrative privileges.

Enable the WMI service

The Windows Management Instrumentation service is required by the LogMeIn Hamachi application to run properly. Make sure that this service is running on your computer.

  • Press Windows key + R to open up a Run dialog box.
  • Type “services.msc” and press Enter to open up the Services screen. If prompted by the UAC (User Account Control), click Yes to grant admin privileges.
  • Inside the Services screen, locate the Windows Management Instrumentation service from the right-hand pane. Double-click on it to open the Properties screen.
  • Inside the Properties screen of the WMI service, go to the General tab and make sure that the Startup type is set to Automatic. If it isn’t, change it using the drop-down menu. Once the startup type has been modified, start the service (using the Start button) and click Apply to save the changes.
  • With the service enabled, start LogMeIn Hamachi again.
