Method 3: Check your antivirus software
The “Hamachi service stopped” error may be caused by your antivirus software. When Hamachi was blocked by your antivirus software, the error will appear.

There’s another situation that Hamachi isn’t blocked by antivirus software. Hamachi may have a conflict with your antivirus software. Therefore, uninstall the antivirus software and restart your computer can help you solve the error.
If this resolves the problem, you can install another antivirus software. But if you are fond of the old one, contact the vendor of your antivirus software and ask them for advice.

Bonus: Update your drivers by 2 clicks
In order to improve your VPN work performance, it’s important to keep your network adapter drivers up-to-date.
There are two ways you can update your network adapters drivers.
Option 1 – Manually – You’ll need some computer skills and patience to update your drivers this way, because you need to find exactly the right the driver online, download it and install it step by step.
OR
Option 2 – Automatically (Recommended) – This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.
Option 1 – Download and install the driver manually
You can download drivers from the manufacturer official website. Go to the website to find the correct model and choose your specific flavor of Windows system (Window 10 64-bits or etc.). Then download the driver manually.
Option 2 – Automatically update drivers
If you don’t have the time, patience or computer skills to update the driver manually, you can do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):
1) Download and install Driver Easy.
2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers. 
3) Click the Update button next to the flagged driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)
