A small but powerful program "Hamachi" is a tool for quickly creating virtual networks, working on the principle of a kind of emulator that allows you to combine computers that are connected to the Internet into a local network system. Despite the fact that this application has the ability to use the so-called gray IP addresses and organize data exchange according to principles somewhat reminiscent of P2P technologies (as is the case with torrents), failures can often occur in it. One of the most common failures is the VPN status error (in Hamachi, the triangle opposite the connection string points to it). By and large, this error is not particularly critical, but when it is eliminated, it is necessary to pay attention to some important nuances, which are further discussed in full.
Brief information about Hamachi errors
In general, if we talk about the appearance of possible failures, almost all of them relate to the inability to establish a connectionbetween computers via an installed client when the so-called peer becomes unavailable.

Typically, most experts cite the following situations as root causes:
- no internet connection;
- application is being blocked by all sorts of security measures;
- virtual adapter is disabled, installed or updated incorrectly;
- failures occurred in the network service of the program.
As you can see, situations can differ quite a lot, but their consequences are always expressed in the same way - a VPN status error appears. In Hamachi, such a failure can be eliminated by several simple methods. Let's start with the simplest, but very important point, which many users do not pay enough attention to.
Proper software installation
We are talking about the first installation of the application on the user's computer or the situation when you update the program by installing a more recent version over the old modification. And this is just not possible. In this case, the VPN status error in Hamachi appears due to a conflict between new components and those left over from the previous version.
To fix the problem, you must uninstall the old modification before installing. But it is not recommended to use your own operating system tools or the uninstaller of the original application for this, since the remnants will have to be removed manually, and if fromIf you don't get rid of them, conflicts will become inevitable. It is better to use some uninstaller program of the Revo Uninstaller class or its analogue iObit Uninstaller, specially created to automate such processes, which remove all residual garbage automatically both in the form of files with folders and in the form of registry entries.
Hamachi VPN status error: what to do first?
No matter how trite it may seem, but very often the most common lack of connection can become the cause of a failure. Users, alas, cannot always detect the lack of communication in time, because very often, for example, when using a wireless connection, the status of the Internet connection icon indicates that it is, but in fact it may not be. To check its status, simply open any of the browsers available on your computer and go to any resource. If there is no connection, look for a problem with the system connection.
Another point at which the VPN status error in Hamachi is also possible is related to the adapter being disconnected.

In this case, open network connections (ncpa.cpl), and if the connection via Hamachi is disabled, select the option to enable it in the RMB menu. Follow the same steps in the "Device Manager", where you may need to enable the network adapter itself.

If a problem with the drivers is detected (for example, after updating), in the "Dispatcherdevices" just remove the existing adapter, and then use the installation of the old hardware.
Antiviruses and firewalls
Unfortunately, for some reason most well-known anti-virus programs almost always block the installed application, considering it either potentially dangerous or unnecessary.

In this case, first, just disable the protection for a few minutes, including both the main antivirus tools and the additional firewalls built into them, and then see if the error has disappeared. If everything is fine, just add the program to the antivirus software exclusion list.
Restart adapter service
Finally, the biggest problem is the incorrect operation of the network service of the installed applet, which very often fails for no apparent reason. To resolve the Hamachi VPN status error, the processes of this service will need to be restarted.
To do this, call the Windows services management section (services.msc), find the Logmein Hamachi Tunneling Engine component in the list, double-click to open the settings editor, stop the service by clicking the appropriate button, save the changes and reboot the system (although this is a prerequisite is not).

After that, repeat the described steps, but with the service enabled. Pay special attention to the start type field. It must be set to start automatically.
How to fixVPN status error in Hamachi if all else fails?
In theory, after applying the methods described above, the problem is usually eliminated. But it can be assumed that the Hamachi VPN status error in Windows 7 or in all related OSes could not be fixed in such ways. In this situation, only a complete removal of the program will help, as recommended above, with re-installation. A similar solution can also be applied if, for some reason, neither the connection being created nor the network adapter are recognized by the operating system, and the specified components are not available at all in the lists and sections intended for displaying them.
